[Mailman-Users] Digests not getting sent

Hello,

I recently upgraded to the latest 2.X release of Mailman. Ever since, my digest users have not been receiving their emails. Can't see anything in the Mailman logfiles that indicates a problem. Is there a command to try to manually send the digest, and if I can do so, where might I watch for issues? It has been a long time since I've done any Mailman admin stuff.

Thanks, Kevin
