As a general rule, provided you have reserved the range in the forum in the usual way, and I have kept my local records up to date, then you will automatically receive credit.
Even when I'm not able to keep my local records of reservations up to date (due to lack of time), I do keep an eye on my "errors" file where I am kept informed of any factors which cannot be atributed to users, and instances where a range reservation can't be matched to a user because forum and SoB names are different. I always try to fix these as soon as I see them.
So I guess what I'm saying to everyone is if you submit some factors where you weren't logged in, and you don't seem to get credit for them, then (say) one week later shout.
