I think that most of us CHAC members make greater use of other club benefits than of the website. So we've joined so we can post, but we'd rather spend time offline crafting than online talking about crafting.

(Plus there are other, preexisting, craft forums that were already very large before this one was created, and many of us belong to one or more of them, making this one somewhat extraneous. And less valuable, since there
isn't as much activity.)
