So Invisible Castle is down!
But I have found a solution!
It's called rolz.org and here's how to use it.
First you go to http://rolz.org/group
It should look like this, follow the instructions in the pictures
Here's a link to the roll picture
There would be an example of an embed here, but it turns out that the forum doesn't let you link pictures that don't have a file extension on the end.
Keep in mind all the rolls you make for a room will be visible for viewing in it's log.
