Highlights & Top Issues for MSMQ on the Microsoft Support site
You'd think that by now I'd know where all the web content for MSMQ was on Microsoft.com but no.
Here's the page for Highlights & Top Issues.
Hmmm.... "Last Review : 30 July 2009" but the KB articles referenced are all at least 3 years old. I'd best find out who owns the page and get it refreshed for MSMQ 4.0 and 5.0.
