I think maybe I should explain what I mean by "Sometimes I add Links to my Step by step Index, and sometimes I delete some".
I'm not actually deleting any of my Threads, either in Whole or in Part. What I do is remove the link from my Step by Step Index. It is still on the forum, if you know what words to use in a search, but it will no longer be one of the Threads that are on my Step by Step Index, that so many people tell me they use regularly.
Other than that, or any spelling or grammar I have fixed in the past, I think the only time I ever screwed up a Thread on SMF, was during the first few days after we changed platforms here. I was fixing my pictures that were lost due to the Photobucket Attack, and I screwed up one of my Old threads. I tried to get it back to the way it had been, but I just couldn't figure it out, and it was giving me a freaking headache, so I told Brian Mudd about it, and asked if he could fix it, or just delete the whole thing if that would be easier.
That was years ago, and as far as I know that's the only time I ever messed any thread up.
I don't really pay that much attention to things being deleted, but the only ones I ever noticed are when some guys get disciplined by a Mod, I've seen them get mad & go back and Delete everything they ever posted, before they get Banned.
I never did that, but I guess removing 38,000+ posts would take more time than I'd want to spend to get rid of all the threads I worked so hard to post.
