Avatar Upload Settings
Don't Forget!
If you haven't already done so: upload the files in the "additional-files" directory to the following locations.
avatars/ - directory to the location specified on the admin page, rename if neccesary.avatars/default.png - default avatar image into the directory created above.avatar-upload.php - bbPress root directory.my-templates/avatar.php - your my-templates/my-template-name/ (or bb-templates/kakumei/) directory.
Read the readme.txt file that came with this plugin for more detailed instructions.
