We are a bit out of sync on our replies, but a new username is up to you. This account will be unbanned in two days. If your children do well sharing an account, I would see no need to purchase another one.
The main benefits to each player having their own account are:
* If one gets in trouble, the other is not penalized
* Each player has their own money
* Each player gets to select their own 4 jobs
* Each player gets to select their own 3 homes + a home bed
* Each player can be uniquely identified in the community
Benefits to sharing an account include:
*Reduced expense while learning to play or finding a server they like
* A great way to teach sharing
* A nice way to improve problem solving skills
* Math practice learning how to spend/share money they have earned on the single account
* Working together to create home areas and both having full access to all player protections without having to modify the protections to allow one another
With Minecraft, you have to actually purchase additional accounts to have other user names. This is not a Famcraft thing, Famcraft is a privately owned public server and is not in any way affiliated with the maker of the game.
To purchase additional accounts, you would need to visit the Minecraft website here:
