Hello
There is apparently some issue with the install or something as it is not getting your .css file. If you try to visit the .css url you get an internal server error:
http://n22.awardspace.com/forums/bb-templates/style.css
I am not sure what the easiest way is to fix this but I would uninstall and reinstall it again making sure all the stuff in the config.php file is accurate.
Someone else may have a easier solution.
Hope this helps. 
Hello
Look in the bb-templates folder for style.css. Copy that to a new location and make the changes then upload your edited file.
Hello
With this you can set the thread to read “resolved” or “not resolved” so to alert other users if the support question has already been answerd to the original posters satisfaction or not.
Then you can also assign “this is not a support question” alerting users that that thread is not asking for assistance.
I did the “bb-admin/rewrite-rules.php” and all is fine except the “tags” links give me a internal server error.
ergate yours seems to work perfectly.

Using Plugins
To use a plugin, simply create a directory in your main bbPress directory called my-plugins and put the plugin file in it. bbpress does not currently have a plugin activation/deactivation interface like WordPress’. Any .php file in your /my-plugins directory will be run.

Hello
I have just begun to make small changes, though it seems to update for me. I just changed the font size in the body section so far.
