how can know about my voting power? sorry i am new here.
Also i see i wrote 2 comment separately here but showing one. why? it's the rules to comment only one in one post?

Only to upvoting/flagging. Currently it's recommended not to vote/flag more than 11 full powered votes per day.

The penalty on more than 4 submissions a day has been removed, so it's "unlimited" again. Comments always were "unlimited".
