Message boards work if you give them time. Sure, you'll meet some yo-yos, but you'll meet good guys too. Give it time and you'll find a group. I made some good friends (real friends, not just gaming buddies) out of a post on the Wizard's Classified Boards.
(Made a few contacts here too, but strangely, got more responses from the WOTC boards. They were good mature players too.)
Also, here's a gambit I tried once. See if you can get the owner of the FLGS to let you put up a small poster sized bulletin in the shop. (Most of em have a bulletin board for this stuff)Mine said soemthing like "London and Area D&D 3e Network" and included a sign up sheet...just date of sign up, email, 1st name and/or phone. Every once in a while go back and check it.
Funny thing was, not long after I put mine up, I found a group and forgot about the sign up sheet...so I never really benefitted from it myself. But you know, that sheet has been up in that shop for 4 years now (its now dog-eared, and they kept adding new sheets when it got too crammed full of names) The shop owner has told me that there's been a great many new groups formed up by guys phoning/emailing one another off that very list. So I'll count that as a win.
Hope this helps.
