Guild Wars 2

First of I didn’t post this in guild section since it seem to be for recruiting this is just a basic question.

If a guild has purchased upgrades/reward with influence for example +5% Exp Public Banner can all member of the guild display that banner and get the bonus where ever and whenever he/she likes. From the wiki it seem hour is 4 hours I guess the banner stay there for 4 hours and how long before you can put another banner?

thanks

- Only those with rights can plant the banner

- The banner seems to stay for about an hour (not sure)

- You have to talk to the banner to get the buff

- You can get the buff for as long as the banner is there. So if the banner is there for 1 hour (I think) you can get a total of 89 minutes of the buff.
