I don't know why, but I also can't see any unit icons today. At all. Even in the default map. SL version 5.1.something, Windows XP SP3 (XP is still a big market for you guys, don't forget that).
Thanks for reading my epically long post and taking things into account.
Let's not forget that alpha means you may still add features at any point, beta is when you have a feature freeze or when you make very small changes in the software development cycle.
Don't be afraid to be bold, this is your only shot at doing this without pissing off absolutely everyone that plays AW (ask your business advisor Elme about market trials)!
I played a bit more today. You should really look into an issue tracker. Most of the popular ones are written in Perl though there are a few in PHP if you are purists. I'd suggest just picking the best solution though, which is Roundup Tracker. Otherwise, MantisBT (which is PHP).
