Brian Gladman has offered vectors for GCM which I’m going to add to LTC. OLPC work this weekend and next, then I resume working on the LTC manual. I plan to offer @cost soft/hard copies after I get all the kinks out (~January). I may offer >cost copies to raise money for my 2007 endeavours. We’ll see. I’d appreciate feedback (privately) from people concerning whether they’re even interested in buying a non-@cost copy. Please contact me!
