As a refresher-I'm happy to re-upload expired clips. The procedure is to leave a "this link is dead" or something similar on the actual post you want re-upped. You can either click on the post title or on the "comments" link at the bottom. That will open a page with a little comment window. Yes, it can be a pain to leave a comment on blogger, but you're asking me to spend a few minutes uploading it, it's not unfair for you to spend a few seconds asking for it. If you make your request on the exact post you want refreshed, I know what you want. Random re-up requests along the lines of "could you re-up that one clip with that one girl I like" or "could you re-do all the Tabby clips?" will be gleefully ignored (and might invite savage mockery).
During my break I got a few requests to renew links that had expired. These requests were all done correctly. Here are the re-ups-
BTW-the process is not instantaneous. I'll probably do it once a week or so.
