Foren / Cotonti / Extensions / User control panel

Yes, I personally use the 240 version from Alexander and creations (but in Cotonti it has many bugs, like disabled comments and a needed core hack in pfs system to assign users folders to a specific category of the usergal structure). I prefer that cause from version 300 authors deleted structure core system and sobstituted it with TAGS system:

What about structure in your plugin?
I think it's a must have.
But I know it's better not to core hack Cotonti... so, urlkiller (in this forum, but I cant' find the post) suggested a structuraction of the gallery probably with page structure system...
