Anybody who happens to know a work-around, feel free to check out: http://bbpress.org/forums/topic/bbpress-in-a-subdomain-on-a-wpmu-install

At least they both use the same theme layout. This should make the process easier (easy is relative). I would love to be able to use a single theme and have it applied to my forum.

But I also load the wp-load.php file in my bb-config.php file

define('WP_BB', true);
if ( !defined('DB_NAME') ) {
 require_once( dirname(__FILE__) . '/../wordpress/wp-config.php');
}
$bb->wp_table_prefix = 'wp_'; // your wordpress db prefix is
$bb->wp_home = 'http://www.trashfilmorgy.com/wordpress';
$bb->wp_siteurl = 'http://www.trashfilmorgy.com';

Then I went into my bbpress theme and changed every instance of bb_get_header() with get_header(), and bb_get_footer() with get_footer().

Since I want to have my wordpress sidebars show up in the forum, too, I also added get_sidebar() right above the call to get_footer().

I could also add other sidebars, too - the theme I use adds two columns below the main content area and uses the dynamic sidebar functionality to add them in to each page. I could see how adding other or more sidebars and going in to the templates could be really useful

1. Point its CSS to the corresponding WP themes CSS so that there's a common stylesheet between them. For example: http://mysite.com/wp-content/themes/mytheme/style.css
2. Do the same thing with images. For example in your bbPress theme use http://mysite.com/wp-content/themes/mytheme/image/image.jpg
3. As mentioned above you will need to duplicate content from WP theme. I find that if I cram everything before the forum content into header.php and everything after into footer.php it clears up the rest of the bbPress templates for me to modify as I wish.

Hope this helps.

You can see what I did for my site here: http://tiptaptip.com and http://tiptaptip.com/forum

And on the bbpress forum, i will have the forum categories in the sidebar, and then just a list of all the topics. So i don't think that'll be a prob :)

Oh and i like the way your sidebar works, how it changes all the time. Pretty cool.

Thanks again :)

To the theme thing.
Yes it's my theme. I forgot to say: the navigation thing i mentioned is only usefull, when you use a self-made navigation like i do. If you use the wordpress sidebar to navigate through your site, you should use also the sidebar to link to your forums. E.g. you can do the following:
Go to you widget options in wp-admin, add a text-widget to you sidebar and write something like:
Visit my Forums
in the widget. Save and you'll get a forum link in you sidebar.
I don't know how to display the hole wp-sidebar in bbpress. I think thats a little bit more difficult. But you could write in your bbpress theme a link above the forums itself that links back to you wordpress.

In my opinion the easiest way to "integrate" the themes is, to use a self-made navigation.
Many wordpress themes use self-made navigations also.

And is it possible to transfer avatar images from bbPress to WordPress, if so, how?

Any ideas? :(

So there is no way at all to make a plugin or something do it for you? That's bad, but i'll have to try :)

How do i do with the menu? I can't link the menu to another page in wordpress. I can only link to pages in wordpress... how do i link it to the forum page, which doesn't belong to wordpress..?

I must say you've (if its yours) done a very good job with your theme, and no i can't see any difference between your blog and your forum, exept that the forum is moved like 5 more px to the left. Awesome job!

of course it is. But not the way you think. You have to work around a little. I'll explain:
check http://www.sumit-online.de/forum/
fully integrated with a navigation that links to my wordpress sites.
BUT:
This is not the wordpress theme! Maybe you can see a little difference in my head-picture between the forums page and the others.
You have to copy/recreate your wordpress theme in bbpress. bbpress uses the same theme system than wordpress. so you do a theme for bbpress that looks exactly like the wp ones. you also use the same navigation. Then i looks fully integrated like my bbpress. But it isnt really THAT integrated. it does the job...

and if you e.g. want to change a navigation menu or something other in you theme, you have to do it in BOTH! WP and bbPress theme.
hope you can figure it out now

(forgot to add the footer on the image..)

So is there any way to do this? I noticed there is a "WordPress Integration" thing in the settings, but thats not what i'm looking for, right? That will just "transfer" members right?

I had some trouble with installing bbpress before, i couldn't login as admin. I played around a bit with it and then i found out that i had to change the settings in "bb-config-sample.php". I'ts a really good forum, i like it.

Thanks.
