Forum profiles can be filled by means of the two forms: the form of managing forum groups and the form of managing icons and smileys.
The form of managing forum groups serves for adding and changing forums groups. Groups are used for grouping forums in the public section of the site. Each forum can be either linked to one of the forums groups or not.
The form of managing icons and smileys serves for changing the available set of smileys and icons. When you add a smiley or icon of the non-standard size, check the appearance of the forum public section. Sometimes you will have to make some changes.
