Adam Towsley and I and organizing a sage-days November 7-10 at the Florida Institute of Technology (
http://wiki.sagemath.org/sagedaysACD). The project in arithmetic and complex dynamics is just getting off the ground and it would be great to have a few more experienced sage users/developers there (general topics of number theory and algebraic varieties). Anyone interested in these topics is encourage to attend and we have some funding for travel and lodging.
See the wiki page or send me an e-mail if you have any questions.
Sincerely,
Ben Hutz
