How many thanks do you have to spread around in order to give thanks to the same person again? Is there also a time limit to say thanks twice to the same person.

 

Some people devote a lot of time and energy to helping people with qualified answers but a month later I still can not say thanks again (Martin comes to mind here).

 

So, what are the rules?

Last I recall the setting for spreading it around is 5 people. I think there's also a limit on rep to the same user in a day.

Your thanks button doesn't work either so thanks.
