AI Thread Summary
Necroposting is generally discouraged on forums like Physics Forums, especially when it involves threads that are years old and no longer relevant. Posting in a thread that hasn't been active for 3-4 months is often acceptable if the new contribution is on-topic and adds value to the discussion. However, care should be taken to avoid cluttering the forum with off-topic replies, which can confuse regular users. If uncertain, it's advisable to reach out to a forum Mentor for guidance on whether to post in an older thread. Engaging in discussions that provide useful information can sometimes justify necroposting, as seen in examples from other forums.

I got the feeling, that necroposting is frowned upon at physicsforums.
My question is what constitutes necroposting and how to avoid it? I am a beginner so don't know rules in details.Suppose for instance, I have a doubt regarding a thread which hasn't been discussed for 3-4 months. The OP seems to be satisfied with the replies , but I have a few doubts in the reply.
Should I create a new thread and quote the old thread ?

Or , when it ok to post in such a thread ?

Note - the thread in which i wish to post isn't speculative in nature. it is straight maths.

Good question.

3-4 months wouldn't normally be much of a necropost, especially if your additional question is on-topic and would add to the thread.

Necroposting is often posting in years-old threads, where the discussion is largely done. This is confusing to the forum regulars, and can clutter the forums with fragmented discussions that go off-topic quickly.

Also, very often spam bots necropost (because they just search for specific terms in threads to respond to), so a necropost raises flags for the forum software and the Mentors.

The policy on necroposting can also vary a bit from forum to forum here on the PF, depending on the Mentor and their judgement as to whether the necropost adds to a still viable thread, or will just dredge up an old discussion and clutter the forum.

If you want to PM me about the thread you want to post in, I can take a look. Or PM one of the Math Mentors to ask them for their thoughts.
 
The thread I was interested was a maths doubt thread. The OP seems pretty much satisfied by the response. The reply consisted of a way to go ahead with a proof. I wanted to ask if a proof that I came up with is consise enough. I will PM you the thread.

Such a thing happened 2-3 times before too. But I was unsure whether to post or not.

I got your PM and replied. Since the thread is a schoolwork question (misplaced in a general math forum), it becomes a harder question. If you post your try at the proof, you may be providing the OP with the solution to a schoolwork problem, which is not allowed in general. On the other hand, if the OP has left the thread alone for a couple of months, most likely they have solved it and moved on, so your posting your version of the proof and asking if it is correct may be okay.

My advice in my reply to your PM was to contact one of the Math Mentors. One of them had replied in that thread, so they may be the best one to try contacting first.
 
yeah , I PMed one of the mentors who were part of the thread as you suggested. Thanks , issue resolved.
 
I want to thank those members who interacted with me a couple of years ago in two Optics Forum threads. They were @Drakkith, @hutchphd, @Gleb1964, and @KAHR-Alpha. I had something I wanted the scientific community to know and slipped a new idea in against the rules. Thank you also to @berkeman for suggesting paths to meet with academia. Anyway, I finally got a paper on the same matter as discussed in those forum threads, the fat lens model, got it peer-reviewed, and IJRAP...
About 20 years ago, in my mid-30s (and with a BA in economics and a master's in business), I started taking night classes in physics hoping to eventually earn the science degree I'd always wanted but never pursued. I found physics forums and used it to ask questions I was unable to get answered from my textbooks or class lectures. Unfortunately, work and life got in the way and I never got further the freshman courses. Well, here it is 20 years later. I'm in my mid-50s now, and in a...
