We are participating in a international project to activate youth and create printed maps with interesting locations for them. Decision fell to OSM, guess why :D
Around 9 of us will be doing OSM workshops in http://wiki.openstreetmap.org/wiki/Blaengarw from 15th to 18th of January. If you are near here feel free to join us.
We'll also be based in Cardiff during that time, over night.
From 19th to 20th January, schedule puts us in London, probably Greenwich, so we would like to meet with London mappers on Saturday 19th.
Harry that means you ;)
Hope to meet some of you in those places we visit. Feel free to contact me.
