Lisa,
Firstly, I did not see the posting you refer to, so cannot comment on that particular episode.
A short while ago I removed a posting, and that resulted in a lot of petty remarks about moderating, and so forth , so a different method of moderating was set up whereby offensive posts or comments are removed, but the vaild part of the post is left.
Because of the forum setup, the editing area is quite difficult to use, and very slow and cumbersome, so some posts stay on longer than we would like.
One of the options suggested was exactly what you are suggesting, a short ban, and that option is still open to be used.
The Mod team know that some users have great difficulty posting, and they are to be applauded for sticking with it and making valuable contributions, even when the speling and grammar are not exactly perfect, and offensive comments have and will continue to be removed as quickly as possible.
The forum is supposed to be a relaxed place for like minded people to share thoughts, views and technical information in a civilised manner.
It is not the place for personal rudeness to other users for whatever reason, and it is certainly not a place where exact spelling and punctuation are needed, if it were, there would be very few users!!
So far the revised moderating seems to be working well, but please rest assured that persistent abusers of the forum etiquette will have their account suspended if it is necessary.
