The Sims Resource has invested heavily in TSR Workshop with 2 full time programmers working on it since before the game released in June 2009, and who will continue to work until such time as we consider it a feature full, stable product. We also plan to invest in licences for Maya and 3D Studio Max plug-ins at great expense, to allow Custom Content creators to work quickly and efficiently with their tools of choice. The result will be a software product which has enabled masses of additional content for Sims 3 players to expand and enhance their game.

Whether you are a CC Creator making direct use of TSR Workshop, or a player that benefits every day from the work generated as a result of TSR Workshop, we would encourage you to donate to the project, not just as a way of saying "thanks" for the work done to date, but to help us to continue to invest in the future, for Expansion Pack compatibility and better feature enhancements too.
You can donate as much or as little as you like through PayPal via the link here. Your donation would be much felt and greatly appreciated not only by us, but the whole Sims 3 playing/editing Community!

EULA Update:

We have made an addition to the EULA for Workshop which requires websites and other distribution media to link back to the TSR Workshop page at The Sims Resource as a means of giving credit for the development of the software which makes those CC creations possible. The addition is Section 9 and reads:

9. DUE CREDIT
Any website, distribution portal or publication sharing or making available any CUSTOM CONTENT via digital download, CD/DVD or any other Media, must give credit to The Sims Resource as the SOFTWARE PRODUCT developer on their website or in their publication, by title ("TSR Workshop") and by link or reference to the TSR Workshop webpage (www.thesimsresource.com/workshop).
