I have started a bounty on this question about few minutes ago.
Considering this post and not to wasting my reputation(s);
so I have decided to devote the least possible amount (of worth $+50$ reputation) for this bounty.
Consider the following situation:
Someone answers my question and his/her answer satisfies me very well;
Is there any way to award more reputation on that answer?
For the sake of comfortability let's consider there are different answers A, $B, C, \cdot \cdot \cdot$ on my question; and only A satisfies me;
then my question is:
Is it possible to increase the amount of a bounty, to award more on the answer A?
Is it possible to award that bounty on the answer A; and again starting another bounty on it, and award it again on A?
[Is it possible to award two bounties on the same answer?]
Is there any way to show my gratitude for well-satisfying answers?
