Not actually, but here is the offer.

Http://www.gogrid.com It's similar to Amazon's cloud computing platform (EC2).

If you join, use any of the following promotional codes:

GGED
GGRF
GGSB

and you will get $100 in free charge. Make sure that you use a VCC (not your real credit card number) so it's possible to find these credits repeatedly.

Cheapest server is $0.19 per hour to get a windows platform, which can be greater than most of you need. This comes out to 21 days of VPS service that is free. Then rinse and repeat.

I'm currently using this to run some backtesting and optimization runs. Will report back with my results.
