I know this will likey sound silly, but I haven't been able to find where I can post a reveiw of a mud on the site. Could someone explain it to me please?

Find the Mud in the list, using the search engine on top.
Then click on the INFO button to the right of the Mud's name.

This will send you to a page with details about the Mud.
On the top left of that page there is a link 'Submit a review for this mud' that you click on.

Not all Muds permit reviews however, so in these cases the link may be missing, which explains why you might have trouble finding it.

AHA, that would explain why
