The player-versus-player battling system is now complete. It's still not 100% tested yet, though, so I may or may not be overlooking bugs. There is also a wager system attached to this (through a linked trade system), which makes it possible for anything tradable (gold/items/monsters) to be added to a battle as a wager.
Which browsers are you people using? Firefox is recommended, but here's a list of browser compatibility:
Mozilla Firefox - 100% compatible. Recommended.
Internet Explorer 7 - mostly compatible, but due to IE7's default caching options, trades will not update correctly unless you change your caching options (I've written a guide on how to do this)-- after changing that, though, everything should work 100% perfectly.
Internet Explorer 6 - somewhat compatible. The game works fine (probably suffers from the trading problem that IE7 suffers from, though I haven't checked it), but the page displays improperly due to IE6's poor CSS support. Microsoft didn't fix that until IE7.
Be reminded when the alpha launches:
On the website, you can now add your e-mail to a reminder list if you wish (optional, obviously). You will then be sent a notification e-mail when the alpha test launches (and possibly when the beta and official game launch-- other than that, no other e-mails).
