I think a GLDCoin donation address needs to be setup and managed/overseen by MicroGuy and his trusted staff to allow folks to donate to the cause. This could be used to fund/encourage development and participation.
Perhaps there is one already. I don't know.
Hopefully, some of the big time miners we see at some of the large pools will donate appropriately to ensure that their investment pays off. I know I will and I'm not a big fish.
