Well guest accounts don't need to be max accounts so while there may only be 40-50 of us that have max accounts and can do beyond that some of us could make several accounts and really up the number of people playing pretty quickly. I would probably try to get quite a few of my family playing and several friends.
Also don't discount it for economic impact for the business minded out there.
Sure, I like the idea. I'm just wondering if there is enough demand to warrant doing the dev work.
That'll be up to @aggroed and @yabapmatt I guess.
I'm not sure if it's very hard at all. Maybe @asgarth can even shed some light on it.
From my understanding an easy UI that creates a username and password (or perhaps only a password)
And in the backend limitations to what a user can do when logged in with that password/guest account.
It really could be that simple.
