I love no edit button. I’m a member (not as busy of course as I am here) on a few other forums and the edit button does allow to correct mistakes, but people can hide behind it too easily.
Here - what’s said is said, and can’t be unsaid; unless the Mods remove it of their own accord, or sometimes will if you ask pretty please...
I've seen individual replies go away, and I've seen entire threads disappear, but neither can be editted.
