The UnrealIRCd team does not officially provide support for any services packages that you may be using or want to use. This forum is provided so the community can help each other with services issues.
If there's an error in the language translation, submit a patch to the developer of the services package you use.
Depends on which services you use. For IRCServices you have to change the setting in defs.h and recompile. (I just answered this question over at servicescommunity.za.net)
