I just went through and fixed all of the posts (mostly scripts I shared) which referred to attachments which weren't there anymore. When I migrated this site to the new software I'm using a couple months ago, the migration tool didn't migrate attachments. All of the attachments from before are now back where they were, just as normal links since this new software platform doesn't support attachments directly. I apologize for any inconvenience encountered if you found a broken link.
