how to use ar?

sorry for the earlier post, so long haven't use liao lol. So I created Another blog, originally in 2008 it was demolished hoping it would never ressurect. Well clearly now I have a lot to talk since my school is begining to look more crap than educational, so to those limited viewers who see this I hope you get the message that MARIS STELLA HIGH SCHOOL IS DANGEROUS FOR YOUR HEALTH! Anyway my blog seems very empty now but improvements will follow... eventually....
