annotate gpp/membermap/signals.py @ 260:3a4bbf9c2cce
Fixing #107. Apparently some signal handlers were getting connected twice (double import?) and thus saving a forum post would cause 2 email notifications to go out to the post topic's subscribers. Use the dispatch_uid parameter in the connect call to work around this issue.
