Just thought I'd post some hints from time to time to hopefully cut down the number of applications sent to me that then need patching up, and also so anyone who wants to can publicly ask questions and that way others may see my answers (if I know the answer!)
So to start with:
Simultaneous Events
If you are arbiter for two FIDE-rated events in the same place and on the same dates (eg a main division alongside a reserve division, or a seniors event alongside an Amateur tournament) you can only claim one of them as a norm towards any given title application.
