[sage-support] synchronizing local Sage worksheets
I regularly work on three different computers. What is the best way to keep worksheets synchronized that were created using a local Sage Notebook? If I create a worksheet in on one computer, I've had to remember to upload the worksheet to the other local Sage notebooks. There must be away to automate this. Some info: 1. I'm running OSX 10.6 on 2 computers and 10.5 on the other. 2. I use Dropbox to synchronize data across my computers, but haven't created symlinks to anything in my sage folder. 3. I've put sage in my Applications folder. Thanks.

[sage-support] Finite Dimensional non-commutative algebras
Are there any classes for computing with finite dimensional non- commutative algebras? I know (but don't know the details) that GAP has some support for that, to compute things like ideals, and the Jacobson radical. And, I think that SAGE has some support for group rings, but I was looking for things in more generality.
