You can discuss ideas here, but if you don't feel like going through a full discussion phase or what not, feel free to just use the internal system and wait to see if I implement the idea or not. Just because ideas are discussed here doesn't mean I will implement them, however, I can be swayed by a good argument. Bugs are generally not discussed here and are fixed without the need for many eyes to try and exploit them
Comments can again be in either place. I'd prefer one off comments to be kept internal unless they warrant an indepth discussion. Let's not clutter the forum
