The 2 forums are not
the same. This forum (ibmmainframeforum) was started for students and other beginners. The other forum (ibmmainframes) is supposed to be for experienced people (indeed, it is called the Expert forum).
Unfortunately, many people who know less than a beginner and make up false "expert" credentials clutter that forum with really questionable topics.
The good news for people posting here is that mostly the same "seniors" reply to questions here as reply to the ibmmainframes questions.
Sorry for writing non-technical stuff here.
Not to worry - not a problem
