I have a few forum suggestions just to make it more neat, clean and professional. One thing you could do to improve this is add a split section, for example; When you click Server & Forum Suggestions, you can create a thread, add a subcategory to split the two and make it more organized, so when you click server n forum suggestions you can click forum suggestions or ingame suggestions.
Another thing you can do is add a category for power 2 the players, which is a real RuneScape forum thread, but it can be extremely useful for gathering player input, and things they'd like to see, you should put a couple sections inside this category / topic, like I said above to split the categories. Another ex to make it clear though;
Category: Power To The Players! Threads: Polls, Content, Items, Armor, Quests, Mini-Games, NPC'S, maybe even add the suggestions topic to this.
I am aware this is a new board and it's being worked on I'm not pointing out flaws, etc. Just making that clear, this is JUST suggestions to improve.
