Think I might have been guilty of this once or twice...
Frequently, I simply forget what I posted and where.
I recall once or twice where I created a thread then there was a huge firestorm (like cribs) of posts that put mine all the way down the page, so I didn't see them.
I also remember one where a few poeple replied but didn't really seem interested in the subject, so I intentionally let it go on down the page as I didn't want to bother everyone with a thread they weren't interested in.... kind if like those JW threads that always seem to be at the top of the page 😵
