Welcome to Fanpop.
ফ্যানপপ is basically a fanclub site. There are সংগঠন for movies, video games, food, countries etc. In these clubs, আপনি can add photos, videos, ask প্রশ্ন (or reply to them) and everything else written under the club's banner.
However, the things আপনি উঠিয়ে রাখুন have to be related to the club. Since this is a Metal Fight বেব্লেড club, everything uploaded in this club must be related to it.
আপনি can check the terms in case you're not sure what content আপনি may and may not উঠিয়ে রাখুন to a club ->
link But to answer your প্রশ্ন আরো directly; both and more.
Hope you'll have a good time here
