I have suggested this before, but I think although improved, the forums are still horrible to use.
1. Avatars: Wouldn't it be nicer to have choice in the avatars we wanted, rather than just our Spiral Knights?
2. Forum Names: I preferred it when people used their FORUM NAMES to post on forums. That way, people can make comments, and this will not affect their in-game character's name (and other reasons of that sort)
3. Signatures: Everybody loves siggies? They're awesome!
4: Previews: The whole way of posting is kind of messed up. There should be a straightforward way of doing so, and previews etc should be OPTIONAL
I like your suggestions, but I can see why OOO won't change the forums:
1. SK is a game for all audiences, including children. Maybe OOO is trying to prevent offensive pictures from being seen by those children, or maybe they just want to keep it simple.
2.You can, actually. Just create a second character with another name, leaving your forum name different than your character's. You know, those 3 slots you see right after you log in SK...
3. I like signatures, but I guess OOO is trying to keep their forums simple.
4. YES! PLZ! I want this. <.< I hate this posting system.
