If you have crowdfunded at a level below Platinum and would like to upgrade to Platinum to get the rest of the perks, this is where you do that. The minimum is set at $25, but you can set the amount to pay the difference between your current backing level and the $75 Platinum Level! If you are not sure what your level was, feel free to email at laborxii@gmail.com and we can let you know quickly. If you are already platinum and would like to do more, this is a good way to do that!
