First, my long background explanation. Followed by, my actual suggestion
I used to read/post on the forums often, years ago.
Eventually, I got so fed up, I quit coming to read the forums altogether.
Currently, I have been tentatively, occasionally reading the forums.
A friend of mine posted a suggestion thread recently that, of course, had a lot of negative responses. This is ridiculously typical.
This is one of the reasons I stopped reading the forums altogether.
I can not stand the crappy attitudes a large percentage of posters have, especially when it comes to people making suggestions. Responders frequently respond as if they have not even read whatever the suggestion is. Responses are almost always negative.
I have seen, in the past, people post a suggestion that gets shot down by almost all of the responders, and a bit later someone else posts an opposing suggestion that also gets shot down by the same responders.
It has made me believe that the majority of forum posters are simply trolls. They cant be happy with anything at all.
So, that all said...
My suggestion is essentially an anonymous 'suggestion box'. Basically, a way to anonymously (non-PMing) make your suggestion to be read by the devs.
I think it would be best to have a form-ish type of thing, so the poster makes their suggestion and then explains their reasoning.
Because, then posters can make their suggestion freely - without all the ridiculously, trollish responses - and the devs can read the actual information, instead of needing to wade through the garbage.
