Hi

I noticed a translation mistake, displayed on the confirmation of an buddy request.
I bet there are other translation mistakes, but i didn't search for it.
instead of "their" there should be "his/her" or completele restructure the translation to the passive form:
"you has been added to the buddy list of <player>"

EDIT:
ok i didn't know this point of the singular they
but it is used for undetermined gender... So once you know the gender of the player it just sounds fail
(for the usage of "somebody" it would still be right, but here it is defined by the person behind the nickname.)
whatsoever, english isn't my native language but why don't you just use the passive form without using any pronoun?
