I've just been contacted by a book blogger I did an author interview for. Apparently she posted on the forum, it seemed to load up ok, and then it disappeared and her attempts to log in and discover what went wrong result in her getting a 'banned' page.
As she is unable to ask you herself, I offered to ask for her.
Presumably she broke a forum 'rule' but it's hard to find out what is there is no advice, no warning, just a removal of her post and her log-in banned.
