I don’t think admin is concerned about reasonable networking.

Correct. People who participate in and add value to the forum are welcome to “network” and make it known if they think they could help someone professionally (including posting their contact info). If anyone gives you a hard time refer them to this post.

I tried installing a private messaging function once so that people wouldn’t need to post their emails. It was very buggy though. If I get a chance I will look into it again.
