In the parentheses is how they look in Runescape
I've got:

FBL Agent (FBl Agent)
Im FBL Agent (Im FBl Agent)
LDLIO T (lDlO T)
HLGHER FORCE (HlGHER FORCE - Pretty valuable if you're in higher force)

Got tons more but I'm not posting a list of all the ones I have.
They're not rare but are desirable depending on your likes. I've mostly got Band names (better than the ones I posted) and I also got some bashing on religion. I've got tons of short ones with no numbers. They're all made with random emails. I AM NOT GOING FIRST UNLESS YOU ARE HIGHLY TRUSTED.
We'll use any method you prefer to transfer the display name.
