This is the post that you marked "Looks OK":
I have no idea how any of this blog stuff works so please forgive me if I don't use the appropriate protocol... I'm old! lol I have a Challenger panel with a QFP2200T main breaker and need a replacement. I've been hearing horror stories and want some tea experience. I'm a degreed Eng and have a pretty huge b'ground in elec. I sat on a number of NEMA, NFPA, UL CSA and IEC committees so I understand quite a bit about this... but not experience with panel work. Any help would be greatly appreciated. BJ
While you left a comment asking them to post a new question, and thank you for that, choosing "Looks OK" was wrong because it's not an answer to the question. The Stack Exchange model works well because follow-up questions and other non-answers get removed, so that pages don't get filled up with "I've got that problem too..."
Also, marking it as OK can knock it out of the review queue, meaning that other reviewers wouldn't get to see it and help deal with it correctly.
