All nice. I still like the one from #18 (current head, Hugomka), though I'd like it more if the font matched better, like those in #25 (Sarin).
I have a preference for "Database" as one word, and relatively large. Not that I'm anyone.
As for those who would try, the first step is to get a clean logo-- the "Wonderland Online" & spell star part. Of course you need an advanced graphics editor with layers, like Hugomka says.
