What do points do?

Until recently I played only on BC where you cannot earn points. Now that I am on Wotlk, I am wondering what these points actually do. I know you can use them in raffles, but are there other uses?

Sorry if this is explained elsewhere but I cannot find any info.

you can spend Points on Store (icecrown and Frostwolf) and Services (Icecrown, Blackrock, Frostwolf)

Ooh I see. I completely missed the dropdown. This explains it, thank you!
