Hmm, it might be a good idea to also ask DogecoinMachine to update the OP of the thread to reflect an open spot for the Hero Members then - not everyone will look at a Google Doc spreadsheet by default, or go through the thread in the hopes that there is a mention of an open spot somewhere (especially when the OP was updated not that long ago: Jan 27).
Also, increasing the rates might help.

Because having shared best rates is not enough, right?
DcM was ill over the last days, and 4 days is not "that long ago", but OP will be updated soon.
