Hi Tony,
You have 4 posts now, so that shouldn't be a problem.
Although, .... it sounds familiar. Maybe the first time you tried you had less then 3 posts and this information has now "stuck".
Have you tried deleting your cookies, then logging in new to RootsChat ?
I would enter your water gypsies simply as "watermen", and then add "water gypsies" in the comments.

Bob
