I fear this may be a stupid question, but here goes.  When I try to message another member, I  get a response that reads "You are only allowed to send 0 messages a day."  What do I need to do in order to send messages?  I'd be grateful for any help.

Looking at an older post of a similar question (from 2010) indicates you need 10+ posts to send private messages. I have sent messages in the past but now seeing this same thing. Hopefully this helps.
