Guild Wars 2

I have looked around but could not find it in the wiki while in WWW
- does /map talk to everyone including the other two servers ? Or is it just another command for /team
- Is there a size limit on a squad?
- The Road marker banner that guilds can put out what is it duration ? Say if it more than 4 hours how many could you have out at once? ( i know this is really dependent on duration )
- Besides fading lines and pinging on the map is there anything else?
-The commanders Icon does it give you anything any tools or just map icon marking your location ?

Map and team are the same chat and only reaches your map.
I am not sure of the maximum size of a squad.
For your 3rd question: Does this wiki answer it?
http://wiki.guildwars2.com/wiki/Influence

Look at the banners you can get from guild upgrades.

edit: P.S. It’s WvW

the time stated by the wiki is the build time but not duration for other banners it gives durations

Wish i could fix the Q title to WvW but thanks for pointing that out
