It's all the same list: Gmane, Mailing List, Ruby Forum, Nab


Does anyone have any ideas how to stop people from posting multiple
times to this list?

It looks like there is a misunderstanding about the fact that there is
are gateways between the lists, so people are posting a questions to the
mailing list and then posting the identical question at ruby-forum,
nabble, etc.

The excess posts are one thing, but sometimes there are parallel
conversations going on in two threads, which is unproductive.

What about a DRY rule for asking questions?
