About the Archive
This is my very simple attempt to come up with an archival program. Enter the thread number (/tg/ only) and a brief title and one-sentence description and hit Go!; it'll archive a copy of the page for future lulz. Archived threads are checked every two hours for updates until the thread 404s. (I never thought threads would last over two days but 1614919 proved me very wrong.) To refresh an existing archived thread, simply attempt to add it again, and it will be immediately refreshed.
Please do not navigate away from this page once you hit Go!; depending on the number of images, it may take a minute or more to complete. If you do navigate away, the update script should catch anything you miss, but the thread may display incorrectly or with 4chan.org hotlinking images until it is repaired.
Mods, if this script seems too spammy, I can up the checking interval, lower the time limit, or remove this altogether. Ideally, it should mean a simple 12 pageloads for a day per new thread, and it does not re-download images, so the load should be negligible.
