If you are having difficulty with somebody on the site, let a moderator or administrator know. If it was by PM, use the report to administrator button on the PM to forward it to Cindy or Susan. We don't allow site members to be harmed by others but if we aren't aware of it, we can't do anything about it. Any reports made to staff remain confidential and staff members violating that rule lose their staff membership and possibly access to the site.
