-Alternate idea: Make a sig plugin, which would expand --Name to
---[[user/Name]] (the "user/" bit would be configurable). This would be very
-easy to do, although it would need to try to avoid false positives, such
-as `--foo` in C code..
+Or, just make a sig plugin that expands `~~~~` and `~~~` as wikipedia does.
+The plugin could be an editcontent hook, so it would take effect only when a
+page was edited via the web.
+
+I tried implementing this, but to make the link to the user, I wanted to
+use `userlink()`, which generates html. But the right thing to generate is
+really a wikilink. Except for openid, when the best thing to generate is a
+markdown link. Except when the page isn't formatted in markdown..
