Hi Jon- Totally legit. Tom is the program manager for the SCP program here at SolarWinds.
As Dawn stated, the Linked In group is legit. I created it to provide a way for SCPs to connect using Linked In's professional networking tools. It's not really a forum, like thwack, but is a professional network tool to grow a personal network of contacts.
I thought it would be usefull for SCPs to be able to identify other SCPs for networking purposes.
