Wanted to share a modified version of /realm command.
You can change the region to whatever RvR zone you are using. It will display a list of keeps etc.
In addition - It will how "Under Siege!" if the keep/tower is being attacked.
I thought this were good information, for i50 servers, who wanted the players to see where the action were.

Replace the realm.cs command in
GameServer\commands\playercommands
My first upload. - Hope it will be at some use.
