I hate to say it but it is mostly trial and error. I've always tried to associate things with the headings.
i.e.
1. Anything that deals with a specific trip (deviation, recap,check-in, etc.) is under Trips and Services.
2. Personal stuff is usually under Crew Information (pay summary, phone numbers, etc.)


The best thing to do is start on the VIPS homepage click a link then go back and forth until you figure it out.

I know it's not much but that's how I had to do it.
