Educated,I think the lord we know calls himself Lordathestrings.This one calls himself Lordof.So compare:
Lordofthestrings
Lordathastrings

Of course unless you use a name that has already been taken,you won't be told there's aproblem coz the screenname you've chosen is similar to another one that's already in use.
