I don't think that a split in the forum is necessary. I think many of the problems with people posting in the wrong place are people using the app. I have used the app, but prefer the desktop version. I always look at new posts first and never go into individual sections. I sometimes look in the unanswered posts to see if I can help, to make sure that newcomers are not overlooked or ignored.
I'm a Type 2 and would never give advice to a Type 1 on insulin, the only knowledge of it is from reading posts on this forum (I've learnt quite a lot though). I was borderline gestational in two out of my three pregnancies in the 80s and 90s, so if I have any knowledge of the question asked and nobody else is answering, then I will. My other area that I will comment on, no matter what section it is, is people suffering from extreme tiredness. It is not always high blood sugars or rebounds from hypos that cause this, there are physical causes too that GPs often overlook. I know this because I was mis-diagnosed with chronic fatigue when it was Vitamin D deficiency.
