I would like to participate in this campaign if rate for Hero Member is at least 0.15BTC.I think is reasonable and correct rate for so high rank.
0.15 BTC is limited for 5 legendary members. Unfortunately , you cant get it as a hero. But still, 0.1
BTC / 50 posts is high for hero members.
BTW, I have just submitted my form over google form. But it would be nice to check the application from somewhere
