Installing within Vanilla 1.1.2, I had an issue on my configuration that lead me to changing the following lines to get the vanilla post.php page to fully render correctly and to alleviate an error that was preventing the vanilla settings.php page from displaying after enabling this extension and refreshing the page. It was displaying the following error: "A fatal, non-recoverable error has occurred
Technical information (for support personel):
Error Message
The "DiscussionExpirationForm" class referenced by "DiscussionExpirationForm" does not appear to exist.
Affected Elements
ObjectFactory.NewObject(); "

--------------------
Default.php
--------------------

-------------------------To get the post.php page to display correctly-------
Changed Line #78 -
(From) include( $Configuration["DISCUSSIONEXPIRATION_PATH"] . 'library/Function.DiscussionExpiration.php');

(TO) include($this->Configuration["DISCUSSIONEXPIRATION_PATH"] . 'library/Function.DiscussionExpiration.php');
(OR TO) include('library/Function.DiscussionExpiration.php');

--------To get the settings page to load after enabling this extension-----

Changed Line #130 -
(From) include( $Configuration["DISCUSSIONEXPIRATION_PATH"] . 'library/PostBackControl.DiscussionExpiration.php');

(TO) include($this->Configuration["DISCUSSIONEXPIRATION_PATH"] . 'library/PostBackControl.DiscussionExpiration.php');
(OR TO) include('library/PostBackControl.DiscussionExpiration.php');

Cool extension idea. With a little elbow grease it seems like a good starter script to enabling several different date oriented possibilities other than just closing discussions.

this one gave me a problem
i dunno what the deal was

r u sure everything is ok in it?

maybe I did something wrong

Is there a way to modify this to expire based on size of discussion -- i.e. when the comment count hits 500, lock the topic.
