Ok, I'll come here and tell you why I don't agree with these:
1. No. This is for the fact suggestions needs to be visible and discussed. People need to know what has been suggested in the past so they either making a thread about it, or if they decide to, they could bring a new reason as to why the suggestion can be useful for the community. And it needs to be discussed, especially for mods, as sometimes mods are not up for monetized servers or have compatibility issues, which could be overlooked by the OP.
2. Off-Topic serves for people to talk about stuff that is not related to DayZ or DayZRP. No need to remove this section. Plus it also has the great Aron73 Appreciation Thread, an amazing and lovely thread about an amazing and lovely man.
3. No. Believe it or not, DayZRP is the place many people come to fix their game. Most issues are posted here, and most of the time solved. When people that are not in this community go on Google to search for fixes to their issues, DayZRP usually pops up first, or on the first page. It brings traffic to the forums and even people that are interested into the community.
4. It is, but with moderation. People need to have the freedom to discuss about whatever itches the community. If a thread about goes sideways, we will solve the issue. Otherwise I see no reason to make it even more hard to post into.
The forums are going to see some changes Soon™, as to make them more streamlined and user friendly for new people who are not used to using one.
