Let’s assume that you created a new sidebar called ‘bbpress’ via your functions file. This means that when you go to the sidebar manager, that you can see one called bbpress.
Next, take the sidebar.php file from your theme and make a copy. Name it bbpress-sidebar.php.
Here is an example of my bbpress-sidebar.php code.
<div id="sidebar" role="complementary">
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('bbpress') ) : ?>
<?php endif; ?>
</div>
Finally there are a number of bbpress templates that call the sidebar. Replace those calls with:
<?php get_sidebar( 'bbpress' ); ?>
Wrapping up:
1. You registered a new sidebar called ‘bbpress’
2. You created a new template file called bbpress-sidebar.php
3. You edited the bbpress-sidebar.php file to ask for the bbPress sidebar.
4. You replaced all the calls to the sidebar with the new call to the bbpress sidebar.
That’s about it. If it is still causing you problems then I suggest reading a few resources.

*Author avatars.
JJ already thought about this and added in a filter where you can choose to display just the username and not the avatar.
<?php bbp_topic_author_link( array( 'type' => 'name' ) ); ?>
You will see a lot of functions like the one above throughout the bbPress templates. Anywhere you find an avatar that you want to remove and just show the username, simply add the ‘type’ => ‘name’ and your good to go.
**There may be a global way of doing this, but I did not look as I didn’t need it myself.
