This year's Shodan Challenge is now under way. There were some problems with people dropping out last year, so this year's set-up is more casual. There are no specific pairs of mentors/mentees; instead we have a teaching ladder system, whereby you can submit games for review, and review other people's games. There's also an option to arrange friendly matches and teaching games.
Our homepage is a Google group: https://groups.google.com/d/forum/shodan2012 
Any BGA members who would like to come along and submit some games or reviews are very welcome! There's no need for any formal commitment - you can do as much or as little as you have time for.
Andrew Simons will be giving audio reviews at 8pm on Thursdays in the KGS British room.
If you have any questions or feedback, please contact me or Billy Woods (his contact details are available via the Google group).
