what are props for???? and If u get them what are they used for??

They're there so te can brag about it.
It can serve as a memory and such. It rewards a person so they know they are doing a great job contributing to Fanpop. That is, if props are used correctly.

te don't use them for anything. te just get them if someone like your pic o commento o something like that... o in competitions :D
