Okay, so everyone seems to be asking. So here goes:
It's okay, as far as we're concerned, to have an account running a normal team with transfers, and a second account run as a purist team. They're effectively separate competitions, so you're not really doubling up to increase your chances of winning. For the 2013 game a purist team for each tour will most likely be an option within your main account, if you want to run one.
It's not okay, as far as we're concerned, to have multiple teams that you make transfers in. Okay you might say that one's for overall and one's for stage prizes, but when you mess up your overall team and you've got no chance of winning any more, what's to stop you going after stages with that one too? Or going after the overall with both if you end up doing particularly well at the start?
