Comments close down on posts after seven days and then the comment input form disappears.

Your comments are welcome. You don't need to enter a URL and you don't need a "valid" email address, either. Note that MT Blacklist is installed to flag suspiciously spam-like strings. Unfortunately, because of the bastard spammers, the strings "google.com" and "yahoo.com" are currently banned as well. Another common bounce is any word containing the string "cialis" which means words such as socialism will be rejected. Try putting a hyphen into a word like that.
