this is what we've all been waiting for. as you can probably guess, this is a script that can take a bunch of posts tagged with one thing and replace that tag with another. that's what it does! isn't that great?
there are things you need to be aware of before you use this:
in large groups of posts, it doesn't get everything on the first try. if it missed some posts, just do it again, maybe a third time.
this doesn't currently work on ask posts. if you know why this is happening, let me know, because i definitely don't.
as far as weird characters go: colons, spaces, hyphens, apostrophes, and both kinds of slashes now work. ampersands and many other odd characters probably don't. please use caution.
i'm a busy college student and don't have as much time to dedicate to this as i'd like! but if you have questions, i'm @cubeghost on twitter.
