I hope you don't mean me with the Update of posts. If you do and it's causing a problem for you, I will knock it off. I do use that feature to correct typos or insert a word that was left out. (That seems to be happening to me more often; a sign of early senility? <g>). I do not use it to make substantive changes to the post.
I'm with you about long posts that consist mainly of a long series of quotebacks. It's overkill when we already have easy to use thread navigation options. After a few messages it's hard to tell who said what, anyway. No, I wasn't referring to you at all. And while I don't agree with the UT's ability to edit messages, I never would have said anything if it were only used to edit typos.
