Keep the Help files updated!
There's a lot of help in the Community and from MS itself, but a lot of it is conflicting, or old as MS makes changes to the software. There's no real way to know what advice applies any longer. I've been stumped by following old (not bad, just no longer relevant) advice.
It's more important that you can imagine to ensure that the help files are updated along with the software. At the very least date each entry so I can have a clue to understanding if I'm looking at something that was written a year ago, or yesterday.
