Return of Reckoning

Heya,

I've logged on for the first time in 3+ years and a few of my character names have been changed. I've got an error on the character screen saying someone else has the name now and I need to choose a new one - is there any way to get them back?

Also could anyone remind me what the command is to change names in game?

Thanks

Afaik there is no way to get the name back.
The command is .changename
