So recently i been trying to finish my zak jump quest. I tried for few days however i still cant finish it. and i feel like basically quitting =_= is there anyway that i can share my account so my friend can do the jump quest for me?
You can, but only noobs do this. Just asking if the option is available publicly is most likely only going to create more suspicion. Read the server rules.
No, because then he'd get banned. To be honest, I think you need to ask for a permission. I don't know if they'll grant you one though because many things can happen when you're account sharing.
