You probably already know this, but there are quite a few people out there that make this same mistake: Being Open Source'd does not imply that you'll have everything done for you. As a matter of fact, it usually implies that you should do some of the work yourself so that others can benefit from it too! I hate being such a rant, but I've seen freeware, open source, and GPL mistaken and mixed quite a few number of times. (Haven't we all?)
