Every forum that I have ever contributed to has featured posts, at one time or another, voicing the suspicion that there is a cliquish inner circle of favoured people who exclude everyone else from their discussions. I don't happen to agree with this although undoubtedly people who contribute a larger number of posts become familiar with the style and humour of others and relaxed in their company - but that certainly doesn't mean that they are trying to exclude others. Like
@wolfie11969 , I have never had anything except welcoming friendliness and significant help and support, particularly in the difficult early days post-diagnosis, from others on these fora. I have hardly ever felt intimidated, dictated to or excluded by anyone.
I have one
caveat, gleaned from my experience on various online communities and not specific to any particular one. The people running a forum can often take sides on issues like this, based on judgements and opinions that may or may not be correct. Those thus judged can sometimes feel, in their turn, that they are being discriminated against and made to feel unwelcome, with the result that they go and that fora lose valuable contributors and members, which doesn't do anyone any good.
Purely my opinion; other points of view are available
