What does the levels beside my discussions indicate.  

hi ketybhagat! ^__^

if you wanna know what those levels are for, you can click the "what are interest rankings?" blue link above your avatar. ^__^

but anyway, those level numbers represent your interest rankings. interest rankings are categorized by 2 items, one is the level and the other is the rank. interest rankings are generally your rank within a particular interest. ^__^

your "level" within a certain interest will show how you are ranked compared to others who also belong to that interest. the more positive ratings your discussions/responses get within that interest, the higher your level will be. the higher the level, the better.

on the other hand, your "rank" is your standing in a particular interest. you are ranked with comparison to everyone belonging in that interest. the lower the rank the better. ^__^

i hope i added some light to you. ^__^
