You have 2 pending suggestions currently. Your most recent was only posted yesterday, you have to appreciate we get a lot of suggestions and we try to give each one fair consideration so it takes time working through them. You do have another one that was posted 30th August, however sometimes some suggestions are evaluated for feasibility before they are rejected, and often this means running it by admin. Unfortunalty when thats the case it can take a very long time because as you can appreciate he is a very busy man.
Basically the point is, every suggestion is considered carefully, and we get through them as prompt as we can but you must be patient with us. You will be notified when your suggestion is rejected, or you will see it become visible for discussion if its approved for discussion. Be patient.
