Most people don't beg for donations like Kathy did, because most people are not fraudulently using the donations for personal purposes while skimming the budget surplus from advertising at the same time.

Sorry but the Sims is not the only game that has fan created mods that people pay for.  Flight Sim communities have been doing it for just as long if not longer. (An example is here: http://www.realairsimulations.com/list_box.php?page=spit08_buynow )

Most game communities are actually fairly small...While I can certainly understand why this happened, obviously there are some large sites that *are* free and don't charge anything, thus proving that it can be done on a larger scale.

It would make more sense for TJ to just finish adding to the Blender what it needs.
