CampFreddie, I believe;
IOD = Isle of Dogs
IE = Ian Evans - possibly a reference to the previous challenge on the age 60 rule.
P*** U** = considerable amount of alcohol to be consumed (Glasgow is perfect for that)
PDG = Pretty Damn Good (so I'm told)
Sabahan is a reference to being born in Sabah, Borneo
KK = Kota Kinabalu
L+K = Love and Kisses?
PE = Plus Expenses
So I think PEs initial text might make more sense now! Basically I think he feels his subscription monies aren't being put to good use.
