[SciPy-User] Mail list proposal/idea

I prefer the mail list but stackoverflow.com is good. But what I really like about stackoverflow is not the answers but the ability to search and even the dynamic search when I start to type a question. Here are a few ideas 1) When the first email of a tread is processed by the mail serve a search of similar question is done and the relevant posts are attached (as links) at the bottom of the message. 2) A web based interface that is similar to stackoverflow in that a user can search and post within the same page and as they type a question suggested relevant posts are shown. I probably should be posting this elsewhere, like on some mailman list. Do you think this is feasible (cost, benefit) or desirable? Vincent
