PS I made yet another mistake in my above post which makes it a bit hard to follow but if I edit it I'm expected to give a reason for doing so. In my case it's usually one of the following:

1. I tend to hit the send button without rereading properly and notice typos only once a message is posted.
2. Sometimes I want to add something I just thought of.
3. Sometimes I want to delete something
4. The quote thing is a bit arduous so sometimes I have problems there too and chop off the wrong bits
5. Sometimes I imbibe slightly too much wine or chang and this affects judgment and vision.
4. Sometimes I'm just fiddling around seeing what the buttons do.
5. Sometimes my keyboard gets stroppy all on its own ...probably due to sand, green fungus, biscuit crumbs and the wee red ants nest in there.

Why does this forum format require mea culpas and impose a time limit on edits? On other forums you can edit as much as you want and it only shows you've edited if someone has posted after you.
