Cinema4D doesn't have so much need for add-in content. Most of the people using it tend to roll their own so to speak. Plug-ins are usually sold direct by the creator as well. That aside, we have a really good little forum over there (the hot20 even worked!) These forums and the galleries (there are a lot of good works out there and a lot that are evolving quite nicely) are what keep me here.
I guess what I really want to say is that I know Poser pays the bills and I accept that as part of the price to showcase my art and provide a set of forums to enjoy the process with others of similar bent.
Further thoughts, I hang at CGTalk a fair bit as well and that is a tightly run ship. Only thing is, here is home figuartively. Not because of the actual building (site/processes) but because of the people in it and how we all intereact.
Please don't leave.

Pass no temptation lightly by, for one never knows when it may pass again!
