Guild Wars 2

Hello,
I should sound a bit crazy, but is there any option to invite a friend to try out the Guild Wars 2 for one day? Because I wanted to invite my friends, but they said that they will not buy the game without trying it.

(My idea is that we could invite only one friend per account with a link or something like that)

Because of gold sellers, it is not / it won’t be possible. You just have to wait for another free weekend tryout. They do them regularly. And we (the players) will have to endure that weekend full of gold sellers sending whispers everywhere…

I got into the game from a friend. Basically, he came over to play starcraft, and opened GW2 on his computer for me to try. I made a new character on his account, walked around, did the tutorial mission, walked around some more, fell in love, went out and bought the game the next day (I prefer having physical copies of software).
point being that you can have them try playing on your account. They wouldn’t be able to play with you, but I feel that’s not totally needed for an intro to the game.
you could either have them download it on their computer, then you sign in, or have them sit at your computer.
