We've decided to update XKit. It's harder than it looks. We're not in contact with the original XKit Guy, nor do we have access to xkit.info. We currently operate at this blog and on GitHub.
hey- for the anon about editing reblogs, there is a way to do it without the extension, too! if you copy and paste then add the indent, it lets you edit stuff! then when you get it perfectly updated, just delete the text. :)
