I'm confused as to the 'Play Selected' functionality of the new launcher. This would seem to allow to select more than one account and log them in simultaneously and indeed that's how it's been working for me the last few days. I was pretty exited to use this as I'd like to make a new full account and move my market character to it. That way I can keep an eye on orders while I do other stuff with my main. It's been working so far with a trial account but today I got this...

"While we appreciate your enthusiasm to try EVE, we would also appreciate if you could limit yourself to using a single trial or subscription accounts only"

So it seems it's not allowed to do this. My question is, what is the multiple account login for if logging in with multiple accounts is against the rules?

I don't want to shell out for a second account and $20 to move my character if it's not going to work as it has been so far.
