Looking for a local user group in your country? Visit the SAP Service Marketplace for a full listing.
Since this blog started from a question you asked on Twitter, I'll ask that question here:
Why isn't there a space here on SCN for SAP user groups? It seems to me that they are a (big) part of the SAP community and being able to discuss and promote them and their events here is entirely appropriate. At the very least there should be a "user groups" sub-space of the Events space.
There is a document on SCN listing all user groups too: SAP User Groups Worldwide
Many user groups have their own websites and online communities, and they therefore tend to focus their content there. Of course, they're welcome on SCN and I'm sure a more permanent presence would considered.
