This is a list of all the topics that have already been suggested. It is recommended that posters check this list for topics before making a new thread, in case the topic has already been covered. I'll be adding more as I find them.
Newly added items are in Bold.
I've divided the suggestions into sections which are linked below. If I've omitted a thread that you believe is worth putting, feel free to pm me and I'll add it as soon as I do an update. I will try to update the list once a week, or more if needed.
This thread is meant to serve the community, not myself, so if there's something you'd like to see being done differently with this, feel free to discuss it with me. Many threads contain ideas that are simple to explain and don't generate much discussion, so I don't bother linking.
A small correction, my whale thread was about whales with small areas in their stomachs. Of course, houses are a possibility, but I feel it narrows the scope of the suggestion. I don't mean to nitpick, but I'd like to help ensure the accuracy of such a fantastic list!
