I just want to install invitation system to my forum!

You are not allowed to install stuff on forumotion severices. It might harm the forumotion's databass.

what should i do, to make that invitation system- i do really need it?
if i buy a domain- will i be able to make, install it?

Its forumotions databass so you cant install it still. Unless you change host.
