The current sorting priority is:
2. Oldest account first
I don't think this should change.
Why is the creation date of the bitcointalk account an important factor?
So if your account is older than mine but we send the same amount of merits for the same post, your name would appear before before mine every time?
Or change the message to:
Merited by You(x) and: X(x), Y(x), Z(x)...
I agree:
Or the name of the logged in user appears first on the list followed by everyone else.
