I've posted this to CICS-L and IBM-MAIN, so I might as well blog about it as well. Please share this message to anyone that might be interested!
A few of my IBM colleagues and myself are attempting to create a new community for System z on StackExchange, covering everything System z related. If you haven't seen StackExchange before, it is an excellent and easy to find place to ask questions, share answers or even just vote on questions you would like to see answered. This isn't an attempt to replace or displace existing communities but to encourage even more knowledge on System z to be shared and discussed.
To request a new community you first create a proposal community and encourage StackExchange users to submit and/or up-vote questions. This is to prove that the community would be viable, sustainable and useful. If you would like to help us support this new community, we would very much appreciate it if you could create a StackExchange account, up-vote the existing questions and propose some new questions.
