I received an email from the exceptionally cool Tribe today, inviting me to join Crimespace, part of yet another social network, this one called Ning. Crimespace is: "A place for crime fiction writers, readers and lovers to schmooze, booze and draw up plans for the heist to end all heists. Find new authors to delve into, make friends and plan that heist, discuss the latest in crime fiction and make the place your home. Join up and enter the forums, add photos, videos and make some friends. Pull up a chair at the bar and share your poison."
I have joined Crimespace but have not explored it yet. I am not sure if anyone can join or if you need an invitation; if the latter and you would like to join, let me know in the comments and I'll see if I can work out how to send you one.
