Philipp, suggestion on dynamic db-based update field for changing signatures...

Actually, the signatures are dynamic but the HTML output is cached by the caching system . This is no longer an issue in the upcoming version 2.0, after the cache will rebuild in the new version every few hours.

The forum is only a part of the CMS system and not a standlone script like UBB, phpBB or vBulletin. There are already advantages over other forums scripts like the ability to support multiple websites (e.g. NT/Linux Compatible).
