Hi Ken,
I think you received a mailbox is full message because I am new to rootschat.
I found this under 'help"
New members must make at least three postings before being allowed to use the PM facility.
Please note: If you are sending PMs to new members who have less than three posts you will receive an error message, that your limit, or allowed number has been reached. (note that it says your limit, although it actually refers to the recipient.)
Perhaps one more post will open my mailbox
Liz
