Thread:Project:Support desk/Exporting use contributions history/reply

Hmm, the usercontributions api module cannot be used as a generator, so it the answer to your question is, not easily. Furthermore, the api seems only to export the latest version of the page, not a specific revision. (Even with the revids parameter. Sounds like a bug. Filied as 38669)

So really you can only do it by going to each page on your contrib list, and exporting each one. Or you could download a backup of all of wikipedia (which is a little big, but would have your contribs)
