Because I had some questions about how suggestions are most useful for us. I figured I should clear it up a little.
Obviously, first try the search box on the top right. A lot of things have been suggested already, in one form or another. If your idea is dramatically new or different, feel free to post about it. If it only differs on details, please trust us to make it work in game the way we think it should, you can post it still, but try keep it brief (like "xxx has been suggested and I think its a great idea! ").
About posting itself, to give you an idea, a small paragraph like this:
-Hi I really always seem to have trouble with finding iron for making a stove, limiting my food so much I always hungerlock once I reach 15+ citizens. Can we have a fire or something to at least replace a stove while we look for iron? It can be temporary or need lots of materials that are in game but easy to find, or make it very slow to prepare food, or something.
Gives me a good idea, without me having to analyze how to implement this in the current game mechanics that would require a full rewrite of how some things are done. Not to mention all of us are crazy busy and don't really always have the time to read a wall of text with well thought out ideas into incredible detail.
They are both (short and well-thought-out) appreciated, I am just saying that a small paragraph has a higher chance of being taken along due to that you give us an idea without us having to spend 10 minutes reading about the details that generally might not be possible due to how the game mechanics/engine works now.
I hope that clears it up a little.
