I joined a long time ago but never did much with it... wasn't really impressed back then. A colleague suggested I check it out again...and whoa... how far they have come! I found very hard to find contacts at firms I call on... Professional organizations with discussions and resources and lots more! I am super impressed. You can even post your resume and search for an apply for jobs there!
Oh...and I found 2 jws I haven't seen in 40 years... and asked them to join my network! I don't know if they are in or out...but this should be fun~
