I would be down for anything that involves working on making the forum a tighter unit. Active moderators are not important now, but when it is a case of clicking a couple of buttons, it doesn't make sense to me to not think about doing that.
New graphics would be nice, at the very least get rid of the Vbulletin part and have a simple Fluckit logo there or something. As for colours and layouts I quite like what it is now.
I would like it if we could upgrade any of the thread tools, there are loads of things on other forums but I dont know if its just a case of activation them or something so I don't know if that is possible. I especially would like a "Spoilers" tool to create hidden text that people can expand, would really neaten up certain threads, like the P:S ideas thread.
As for new memebers, I am actually all for it.
If we got cool new members than that goes without saying that it is a good then, if we get n00bs and griefers, then we can either ignore them, suggest how they might improve their behavior, or the new Moderator teams could temp or perma ban them.
