there used to be a suggestions channel, but now that's only for staff.
I think they removed it because there was no real way to keep track of the suggestions that were being made, so to slow down the income they removed it from the public.
it's not like it would do much help, I don't really see them taking any of the meaningful player suggestions serious
but I guess adding this channel would create more hope, or at least another place for the community members to discuss ideas.
