Actually, like a few others here, I'm quite old to the Neo Geo scene, in terms of forum participation. But as a member, I'm kind of new to this exact location. I was a part of the Neo Alec group, info sharing, and of course adding to the "Signs you play too much Neo" list. I was typically known as either Akaimizu or AkaiCham (my favorite avatar was Cham cham on that site). After that site dropped, I was kind of orphaned. I was in the early stages of providing a web site to distribute various Midi files and other musics that I compose, as soundtracking is also my specialty.
I bumped around quite a few other forums, though. Sometimes on the Neo Geo Pocket forum (SNGP) or on gamefaqs. Started writing my own arranged remixes of a few SNK songs in my spare time from my original tunes I make for other things. Anyway, I did meet (from time to time) Neo Geo owners at cons or other functions and usually they ask me why I'm not on the Neo Geo scene, considering my long term experience with Neo Geo games. Thinking that some of them must've come from Alec's site, like I did, I was wondering where they were going. Well, enough references to this site was enough for me to remember to check it out, one day. Which was pretty much last year. So I'm relatively new, but not so new.
