Price would need to be set based on supply and demand. If the price is too low you might get too many requests that BL couldn't handle. You might make a lot of money if it was low, just from sheer volume, but it would significantly disrupt the flow of the forum. If it is too expensive you simply wont make enough money. I would start at $10 and see where it goes. I honestly think that's reasonable. I also think that some people want to change their name a lot, and that's annoying. So for that, $10 the first time, $15 the 2nd time, and $25 for each one after that, up to 5. Or, you can buy 5 name changes, to be used whenever, for $50. If you want to have multiple accounts, $25 per extra account. If people want to change their name, only want one account, but want their post count and join date reset (so they look like a new user) maybe $15. To incentive is without costing BL anything, you could try to figure out other perks too. If you want to have sig at the bottom of every post $1. Perhaps, if you donate X amount of money, you get access to certain things involving MAPS. Something like that.
Remember though, you are not charging people for anything. It doesn't cost $10 to change your name, you need to donate $10 and you get a name change.
It's late right now. I'll post more ideas as they come to me.
