Only problem is that I don't think I know any of the nine members in question. A couple of the names looked familiar but on checking they are fairly common Irish names and the WAYN profiles don't appear to match the people I know.
WAYN is not quite as sinister and crap as Rapleaf, but unless and until some people I actually know start using it and recommending it to me, I'm not touching it. It looks just like Bebo, Hi5 or Myspace, with a little Dopplr added in; but I get all of that and more from Facebook anyway.
Edited to add: Ah, I see someone else has had invites from most of the same people!
