Here's how this is going to work. Rather than having one one feature vote thread, each feature request or bug report will need its own thread. The first post in that thread needs to clearly state exactly what you want implemented. Please only include one feature request per thread, and only request things you really want implemented.
Bad:
New guns!
You should put some new guns in the game!
Very ambiguous - Add more guns? If so, which? Replace the old ones? Make new models? What?
Good:
Feature Request: Improved Weapon Models
Re-model the existing weapons to have more detail and higher-resolution textures.
Also clearly state if this is a new feature you want voted on, or just an idea you wanted to discuss. If you want it to be voted on, it will be added to the new voting system (kindly provided by sk89q) so people can vote for or against it, and the thread will be dedicated to discussion on that particular feature.
Before creating a thread, make sure that the feature hasn't already been requested. If there is already a thread clearly stating a feature request, but isn't in the voting system yet, post a reply there requesting it be added.
