I have a BBPress forum where the avatar upload plugin needs a special integration. The new BBPress doesn't work with the old avatar plugin. The reason is that this plugin was to go in a different folder, but that folder is no longer recognized by the new BBPress.
A previous developer made it work by adding the plugin code directly into thee forum somewhere, but we lost it when we had to reinstall the forums.
I also need the search box feature added to the forum skin. The original developer left it out.
