Probably not many, but as NT manager I used to get bb-mails from managers about their players, how they stack up against others, etc. So I simply replied that I am going to be posting the rankings on the forums.
BB-mail was used as a way to get people to the forums, and once they are there, and the activity rises because of it, it is kind of self-sustaining thing as it slowly drags more people in.
That's the issue imho with being Canada NT. We need somebody who will do much more than would normally be expected from the NT manager. THat's why I am not a candidate - don't have time for it all, but happy to help whoever is elected.
So for all candidates: if you aren't willing to go quite far and beyond what needs to be done in 'standard' NT job - please select a different country. I think youtube might be a bit of an overkill, unless you are an algorithmic wizard able to bring people from outside of the game, but that's the sort of enthusiasm and commitment we need overall.
