I think TelcoLou would be a great candidate. I don't believe he codes for the GP2X, so he spends more time in the forums. Also, from my impression of him, he understands when a noob could generally use some help getting aquainted with the community, when you can have some fun, and when a thread has just gotten out of hand to where it needs to be closed.
I also think Squidge and Skeezix would be good choices, but that is only if they are willing to devote the time required to becoming a mod. (Frankly, I'd rather they not do it and spend more time making great apps
, or, in addition, choose another mod who will actually reduce the work load for the current mods)
Vimacs, I don't think would be a good choice. I know he contributes to the dev community and is very capable of thoughtful and intelligent posts, but he isn't very nice to the noobs
. I know many posts from newcomers are repetitive, vain, or uniformed, but it takes some time to get aquainted with this community, and Vimacs isn't too understanding of that fact (at least not enough help them out).
