I want to so the people who haven't been messaged about this will know about this, but I don't know what the mods of @U2 would think of that. Advice?
Personally I think it might be received badly if we advertise this place openly in the @u2 forum, so I am approaching good and regular users by PM to invite them here. We want the mods to relaunch that @u2 forum after a short break at most, so let's try and be sensitive to their feelings as best we can. PM-ing takes time but we can reach the best posters that way.
I agree with this. If you notice a poster whose posts you like, send them a PM and invite them over here. You could even create a small script like:
"Hey, I've been a member here for a while and was sad to hear about the forum closing. A good number of members are joining a new forum called forum.talku2.com and I'd love it if you would consider joining us over there."
And just PM that to whoever you want to invite, even if it's someone you haven't PM'd before but maybe have otherwise interacted with on the forums.
I don't want to step on any toes over there since the old place has been running a great forum for many years, but I do want the users who want to keep active to feel welcome here.
