It's annoying when I post a suggestion with lots of input/discussion early-mid age and the suggestion is gone from the forums by end of age when the suggestions are actually looked at more in-depthly (for age changes).
My suggestion is that suggestion threads do not "dissapear" from the forums after X amount of time, like they do currently. Keep them indefinitely or at least the length of 1-2 ages. That way we can use a search function or look back, so people don't make the same suggestions over and over and over.
Cheers
