If you have a problem you should try talking to or sending mudmail (in-game mail) to a DM or CT online before emailing. You will get a quicker response.
If you'd like to make a suggestion about something you'd like to see on Isengard a good place to say so is at the Isengard Message Board. The boards are regularly checked by both players and admins.
Have you made a map of an area on Isengard? Or have you done some Isengard related artwork? Submit it to us and let all your friends see.
As always, any suggestions about the website, or comments in general are welcome and encouraged.
