If you want a limb to be replaced with auto mail, you may. If you lost a limb in a thread, you get the basic auto mail for free, unless you intenitionally lost it. Staff members will decide if you lost it intentionally.
The way auto mail works is you buy the basic auto mail, and may pay at any time to upgrade the auto mail. Any upgrade with a * next to it means it can be purchased any amount of times, ** means once per limb, and you may only have one abilitiy with ** next to it.
