WvW guide help/suggestions

I am going to make a WvW complete guide to help people with basic to very advanced tactics/tips. First I need people to give me ideas on what should be included inside. There is so much little things I need to think about that I need help here. Drop comments about what you expect in guide.

I expect it to include:

How to move against a zerg/hammer train.

Where to place yourself against enemy arrow carts when taking objectives.

How to deal with ganker thieves.

Mesmers and you, which one is real?

Gather nodes, yay or nay?

How to join a squad! :D>

What and how rellay information on raidcall? (Example "JQ is near!" vs "20+ JQ Zerg behind us")
