On the "Age" thing, don't even go there we have members in their 90's who get shot down in flames for calling the "Age" Card. I'm just 71 and, more than likely, there's a 17 year old reading this.
Unfortunately, in this Forum, once you've hit the "Post" button. That's what you've get, unless you grovel to FE and he makes the change with his Silver Mouse. But don't press your luck, he might weaken the once, but is unlikely to weaken a second time!
The technology is available but using it makes for sloppy composition and allows people to Post one thing and then change it, after others have replied, which might make them look stupid, which few of us admit too. Amateur - Yes, Enthusiasts - Yes, but Stupid - No. Unless you think that trying to help some damn-fool whose just done something unfortunate, is stupid.
