I would like to attend one of these meetings one day, and having more than a day's notice would really help!
As for short notice, I emailed everybody who expressed interest a few days before announcing it, to check if everyone is fine with the date. Just email me, and I'll keep you informed about everything.
The second meeting will take place on Sunday (2009-05-03) 14:00, in cafe on top of the Waterstones bookstore near the Piccadilly Circus Tube station.
If you want to know more, email me (Tomasz.Wegrzanowski@gmail.com) for details. Or just come straight away.
If you're wondering what it will be like - here's summary of the first meeting.
