The only place where you can make suggestions is the forums. Anywhere else will be ignored or forgotten about.
Make sure you put enough time and thought into your suggestion. Just posting "this sucks remove it" or "add this it would be fun" is not enough effort. You need to think about why it's there (or not there) in the first place, what kind of impact it would have to change it, and how it would affect players other than just yourself.
Remember, even though it might seem like it's a small amount of work, even small features often take at least a few hours of development and testing. Bigger features often take days, weeks, and sometimes even months. Developers have to go through hundreds of suggestions and spend hours or days working on them. So it might take a few minutes of your time, but that is too much to ask for, you'll have to ask yourself if your suggestion was really that important to begin with.
On top of that, most suggestions have an impact on the economy and other features of the server, so it requires a lot of brainstorming and discussing to make sure it does not cause any major issues or unbalance certain groups or players.
For all these reasons, most suggestions will either never be implemented or might take years before they are. Please avoid reminding management about them - if you posted it on the forums, it'll be read and considered.
