can anyone help me i want to be a fan of callian but i dont know where that button is to be a fan!!!

it should be at the top of the banner "area" to the right, it shoud say the number of fans then join bellow it, just click that :D

Look up and to the right. There's a green rectangle that says "255 fans". Under it is a link that says "become a fan". Click on that.
Hope that makes sense :)
