These are threads that I view as important for me to keep links of for myself, which may also help out other people:

General Request Thread - A thread where you can post your characters for artists to look through and draw for you. It's pretty much a free art thread for you.

The Freebie Bin - A thread for people to give away characters/adoptables that they no longer want. Sometimes there are trades posted there or links to other threads, but for the most part people link groups of characters that you can give a loving home to.

Pokemon Gijinkas - This thread has a lovely person who makes absolutely unique pokemon people. 

More may come later, as I find them.
