Yardiff-
It became a problem to post conversions when creative people started getting smacked down for any adjustments. There are many examples of changes in power with the difference between editions and the folks that were doing the bulk of the conversion work had tried to make adjustments for that, but got into some trouble when WOTC threatened legal action for their updates. That pretty much ended posting conversions as apparently, no one wanted to deal with WOTC's lawyers. However, if anyone knows of some folks that are still making conversions, I would be happy to contact them directly for collaboration.
