best response

A way of thanking to the best contributor of your topic. Make him/her happy by giving her/him a BR.. hehehe We need to be commended at times so I think yes it is necessary.. lol I just don't know if BR gives extra money... hehehe

I don't think it is a rule but noticed in the guidelines it is there as a do so I guess it is something we can do. :-) I did not do it for a very long time but then felt guilty about it so went in to the unresolved tab and completed them. After reading what owl wrote here I think I will look at this feature now on a regular basis.

its not urgent i think but as the best, you can keep relationship with your respond with choosing one of them as best respond

Nope, It's not necessary to give BR to someone. In my opinion, give BR to someone depend on: 1. What kind of discussion that I start 2. What kind of answers that I got in that discussion

It is not necessary, but you may give some sort of happiness to the receiver by doing so.

It is not necessary. It is up to you if you will give them the best response mark or not. I seldom do it because there are times I forget. Happy mylotting!
