About 20 people turned up for the first one. I thought it went great.
Lots of people signed up for the 2nd one, but only 4 turned up (including me).
Only 5 people turned up for the 3rd one.
About 80 people had registered with the group, but only a fraction of them ever showed (cunningly meetup.com encourages members to join lots of and then charges you more if you have more members).
So I stopped paying the sub. No-one else took it over and meetup.com has deleted the group. It's a pity it didn't work out, but you don't know until you try.
Another meet-up started in Swindon about the same time and they (so far) provide free food and drink!
