What exactly is the problem?
Do you know for a fact that the member you're trying to reach has Private Messages turned on? Some dont....
You sent a message and never got a reply? How long has it been since that member was actually logged on to iboats? Maybe your message was sent but they are no longer active.
What member? There are other reasons you may be unable to reach them.
If you dont want to post whuch member, you can send this info to any Mod and they can help look into it
I sent you a Private Message, reply to it to confirm your PMs are working correctly....
also, try to avoid taking discussions and Q&As into private messages. That negates the whole purpose of a forum, PUBLIC access problem solving.
