I've updated the Application Database todo and sorted the list according to each item's difficulty. You can find the todo list at http://wiki.winehq.org/AppdbInfo This list is by no means complete so if you have an idea for a new entry feel free to email it to the AppDB mailing list at appdb@winehq.org or just update the wiki page.
I also wanted ask that people interested in hacking on the AppDB take a look at the todo list if they might be interested in getting involved with AppDB development. The php code that runs the AppDB is available from the winehq cvs server and I'm available to mentor anyone interested in getting started hacking on the code.
We've had some new developers and I wanted to thank Alexander Sørnes for his recent contributions to improve several areas of the AppDB that users see most. And of course thanks to all of the other contributors that have helped to develop the AppDB and the AppDB administrators that process all of the new submissions that come in each day.
