Thanks everybody! I have three volunteers now, which should be plenty.
TradeMaximizer assumes Java 1.6. Unfortunately, Macs only support Java 1.5 (except in a preview version of 1.6 that casual users won't want to install). I'm working on removing the dependence on 1.6 so that TradeMaximizer can be run on an ordinary Mac. I don't have a Mac, so I'm looking for a few testers with Macs to try it out.
Here is what would be involved:
1. PM me your email address. 2. I'll mail you a zip file. 3. Unzip the zip file, and run the program. 4. Report the results and/or any problems back to me. 5. Repeat no more than a few times.
