IMSC, not free, but Pam, the President, knows MSCs and allows questions...like this forum, but made for the IC/Shopper, open to MSCs, who can post jobs. It is shopper oriented, and she has all closed/secret pages on FB. You just need to be added to join the pages. You can get info at
info@imscinfo.com and leave a message that you want to join a group...she even has one dedicated to route shopping. You can use my name and tell her I posted the contact email address...and that you are interested and want to see the groups are what you are interested in.
Oh, MSPA has two different memberships, one free and one paid. The paid one has more benefits, like 24 hr advance access to the job boards. Hugs
