Lets answer few questions:
What kinds of things can the regular community do to help this coin progress?
The best way to support Reserve Share is to keep the official thread live, write constructive posts, share ideas.
I have kept the signature. I am eligible for both the rounds?
If you had Reserve Share in your signature when you registered then ,YES.
already become first round share holder ,but still need update signature? oh no , i can't change my signature
No. If you don't had the signature when you registered, then you were qualified only for the first round.
How long do I need to keep the signature? My current campaign allowed me to keep multiple signatures till the end of this month. I am hoping the second round will happen before that.
As it's writen in the OP you need to keep your signature till the end of registration period, which was 08/25
The Final Shareholders List of the first round will be released in few hours. Till then we'll process all the registrations, Facebook validations.
As we mentioned yesterday we accept donations. We will use the donated amounts to the official website.You can find the donation addresses in OP, also i will post it here now.
