Is it possible to have multiple people onlin at the same time, using the same accountbut different characters?

No. If someone logs into an account that is already logged in, the already-logged-in account's connection will be terminated.

it would be cool if you could have two charachters active at the same time but no more than two

i dont see why not well cept for the small decrese in income but it would be minor

another option is you could pay 15$ a month but you could have more chars active at the same time

with a limit obviously

10$ 1 char
15$ 2 chars
20$ 3 chars
30$ 4 chars
ect

What exactly is the benefit of having more than one character online at the same time (besides cheating, and saving a minuscule amount of money? You can save more money by not smoking if you do. Smoke, that is)?

I think it's a bit mean to say 'the small decrease in income'. The developers have made it pretty clear that they don't have much room to stretch out, so if you want to play, you pay.

true toshiro but it would be nice for me and my brother and if i want to give some cash to my alt or some cargo im just throwing the idea out there :)

That is exactly what I mean. Trading between alts should not be encouraged. I am aware that it can be done quite easily using a second computer, a trial account and a few minutes, but that is already a sufficient deterrent for some. Things should not be facilitated any more in my opinion.

If you want two subbed characters online at once, buy a second account.

i will in good time cunjo
