Mike Cooper here. After spending a month chasing people down for the first EU Roundtable series, I'm gonna give interested parties the opportunity to come to me this time. I probably won't be able to include everyone who contacts me in one (unless I'm severely overestimating the response this will get), so if you have a website that properly displays your SW expertise/eloquence, that's a big plus (on top of which, it gives me something interesting to mention when I introduce you). Relative prominence on forums such as the Jedi Council, the Galactic Senate, etc. doesn't hurt either; I obviously wouldn't exclude someone who seems like they'd be an interesting Roundtabler (hey! I invented a new word!) just because they're not well-known, but people are probably more likely to be interested in reading what you have to say if they recognize you ("hey! it's that jerk The2ndQuest! what's he going on about this time?").
In any event, drop me an e-mail (preferably with the word "roundtable" in the subject line) and give me the lowdown if you want in. I'm looking to start conducting these things sometime in the next week or two.
