Number beside our names??

Number beside our names is called "ranking". Its the number of posts to whom we have responded. 189 is coming with urs name it means that u've responded to 189 posts. But if u start a new discussion on MyLot and before writing tage u get respond that urs raking will increase with the numbers of responds which u'll be received for urs new discussion before writng tags.

I think it must be, because it changes everytime I make a new response.
