I am new here, but have been on many forums, Australian, and world wide, U.S. etc.
I love the fact you brought up the topic about having a section just for moaning, bitching, about anything we like!
I know what you mean, that perhaps this area is for that, but in my experience on other forums, if you do have a rant about something and really tell it like it is, in the "patient forum"; you get comments back saying "you're being too negative", etc; when that shouldn't matter, if you are feeling negative, shitty, whatever, it's best to get it out, and it is all part of this horrid disease, and treatment/side effects, yet some still get narky if you do it. (I'm not saying that happens here, I'm new so don't know.)
Some people are all about, being positive, (which is great when you can), "don't say too much about the side affects, or you might put others off". Come on, this isn't the Teddy Bears Picnic, and we all know it, so let's not pretend.
Myself, I want to hear all that others have to say, good or bad, it's all information we need to know. As I've said, if you can't cope with it warts and all, then you would just avoid the "Rant and Rave" section, easy.
So, yes I agree, put up a section that is for bitching away as much as you want, however you want.
Then if others don't like it, they don't have to go there and read it, I know there are others that feel the same way.
Anyway, I wish you all the best,
