Am i need ToriPrime / VIP to change my usertitle ?

yes, that's one of the many benefits afforded to those that purchase.

you can alternatively pay someone higher up to change/remove your title but that takes a bit more doing

You mean...i can pay someone without purchasing ToriPrime/VIP ?

Certain forum staff have the privileges to modify user data so they might allow you to give them a payment of tc for a one time change (at least they did for a time). I'm out of the loop on who these people are though, of course. Asking around on irc might prove fruitful

See my signature for one such offer.

You can also purchase one from the user title shop

So if i buy that, i will pay with TC and i can change my usertitle into anything i like ?

Anything you want which match with general rules "no porn and stuff like that". You can change it only once and then you'll have to pay one more time.

Depending the size, color, symbols and number of letters the prize will raise, of course.

k thx !
