Hi, little doubt:
for the Signature Bounty i know that i have to "make a minimum of 30 Posts in order to be considered eligible".
does it mean that after I reach the "Jr. Member" status after I sign up to the Bounty Signature, do I have to write at least 30 posts?
Or are the post posts made previously valuable?

Example:
If I do 10 post today.
Tomorrow I will sign up to signatoure bounty.
Will the 30 posts of today be counted? Or does the count begin on the bounty registration date?

thank you
