can someone tell me how i become a dedicated tagahanga of something?

You have to add things to a certain spot like images, links, videos, articles, picks etc. and you have to do alot of it :)

You need to ibigay a lot of things to a certain spot, and stay active on it. It also depends on how many people rate your content, so make sure that you ibigay some nice things, that people will like. No spam, or anything that's broken, or has already been submitted.
If you keep doing that after you've received your dedicated medal, than you could even get a die-hard medal, or fanatic medal.

Like RnBstar13 said, u have 2 add things 2 a spot.
Pictures,articles,quiz questions,videos ect,ect.

But u also have 2 receive a certain amount of ratings on eveything u contribute.

How many times has this tanong been asked? A million and one?

OH MY GOODNESS! link
