I would have been happier if CamTu had started a new thread as he moved on to a new topic. Worse, the switch to the ftp question was really a crosspost of this thread and as such was a violation of rule 4. I decided to let it slide. Maybe I shouldn't have. It gets tedious playing policeman.
But in general piggy-backing questions is not against the rules and to the original poster it all may be part of the same project. I'm not sure that such a rule would be a great idea. Neo would need to rule on that.
In the meantime, don't feel that you need to stay trapped in a thread. It took me a while to realize that sometimes I need to bail out of a thread. I don't post a final goodbye or anything. I just move on.
