Michael --
I am hopeful that the ArsDigita User Group (aDUG) program that i'm putting together, along with a successful collaboration with the community on the IB project (and community input on ACS 4) will help go a long way to helping us popularize the ACS (or OpenACS -- to me, the difference between the two should grow smaller over time, and perhaps eventually disappear.)
Thanks for the suggestions, if you've got any more please let them fly. [the more data that me & Ben have to work with tomorrow, the better off we'll all be in the end.]
