We have a busy London Events schedule.

Sat 17th April - Crisis Camp London
Monthly workshop event and meet-up group for technology enthusiasts and other volunteers who get together to work on projects related to disaster relief. They provide wifi and pizza, and we can use it as a place to go and do OSM hacking, but there's also lots of less techy types there who are interesting in learning to contribute to OpenStreetMap (fresh newbies!) So worth getting a few people to go along to this. Jenny and Steve8 are already signed up. I thought this time we could get some people mapping China. Did I mention pizza?.

Wed 21st April - Holborn evening mapping party and pub meet-up
Cake diagram is now available. Sign up! Sign up! Usual fortnightly meet-up, plus I just got off the phone with Stuart Carter, GIS Manager at Southwark Council, who will come along to meet us all at the pub.

Sat 24th April - Open Knowledge Conference 2010
User:Melaskia will be giving a talk about OpenStreetMap Haiti. Thanks to her for taking on that task. Turns out it's only a 15 minute slot. They'll be lots of other interesting topics and people there, so you might like to go along to cheer her on / help answer questions. Or alternatively...

Sat 24th April - Brixton newbies mapping event. Volunteers needed
I see this is as a relatively normal mini mapping party get-together, which I would guess we would have at least five or six people joining in with (and deciding to come at the last minute as usual), BUT it'll only happen if I can get some people to be "the organisers" (just a little bit of commitment to show up 'n' stuff) So if you think you can manage that, please let me know

...more fortnightly meet-ups of course. Plus

Sat 1st & Sun 2nd May - Hack weekend May 2010
A weekend of OpenStreetMap development and design brainstorming, kindly hosted at Hackspace london. Looking at the sign-up list, it looks like we might have a mighty-all-conquering-hacktastic team, at least as a rolling programme with people coming and going.

Sat 5th & Sun 6th June - Another hack weekend / government technical workshop
I've been in touch with people from GLA who want to get talking with OSM developers, and they're also willing to just help us with a venue for hacking too. Waiting to hear back for details on that, but should be good.

Phew! lot's of events, and I didn't even mention the other things going on just outside of London. Hopefully https://www.openstreetmap.org/user/OSMLondon will provide timely twitter reminders. Also the 'London geotech' upcoming.org group has some listings (use the RSS?) But don't forget to sign up in advance if you can, just to help confirm that things are going to happen, and make things look more popular.
