Weird, the yellow has now gone... fuzzy scratches head...
I did have some yellow text in the OP prior to actually posting it but edited it for the reasons you pointed out, never posted it though.....Very Strange.
Anyway, at present the groups are only settable by the highest admins. I don't really foresee any option for users to add their own
I'd agree that allowing users to have any control over this is open to abuse.
My thoughts though at the very least is some kind of indication in each members post of exactly where they are posting from. I admit, i like the idea of member banners reflecting their interests and their native site, but that's not an actual productive feature, where the showing of "posted from" would be invaluable to many.
A great example would be with piderman above. Where Kryo's Stardock banner is piderman could simply have a similarly sized Elemental banner.
Ranks aside that feature would help other users become aware of the other SD sites that are open to them but might just not know about and even increase participation/sales in other parts of the community.
I'm fairly certain these aren't consistent either. Also, last time I saw suggestions like these, SD ended up reading the Riot Act. (I like 'em though.)
Perhaps not. I'm only speaking really of my own experiance in what i have viewed. But it seems that folks like Crazy, Kryo, Zommba, Bara, Brad/Draginol, Shirley, Highlander, Melibee, Zubaz, Jafo.....uhmmm..that's about all i can think of, all those do seem to carry their respective banners across all sites.
In that i would think that such a system is possible to implement. Be it worth the time in SD's eyes is for others to decide but i sure think it would add to the forums.
