I was just wondering how do you think I should handle howto updates on an article I wrote for the site.

As said in a comment, this is completely deprecated due to the new work that the wpa_suplicant maintainers have put into the packaging.

I have updated the original article with the new stuff on my wiki.

How should this be handled? Should I submit a new update article and ask Steve to put an "Update warning" on the old one? Ultimately, I do not need to host that stuff as long as I can easily maintain it. Should this stuff go in the Debian Wiki?

Another weblog post seems to raise the same questions.
