I thought that maybe it will help organize everything and It's a suggestion itself

1. In the subject add at the beginning a category of the suggestion. Ex.:
- [Forums] More skins
- [Multiplayer] Votes and Polls
- [Weapons] Undead Teddy Bear Launcher from Rainbow Land

2. One idea, one topic. Why? Because when someone wants to post an idea, how can he know, if it wasn't already posted in "ideas compilation" thread.

3. Be specific in the subject. No one will be interested in "[Suggestion] My suggestion".

What do you think? Maybe you can think of more
