35 * This plugin could probably result in a lot of confusion, especially when
36 * redirecting to external sites. (Perhaps it can even be used for dastardly
37 * purposes?) Maybe it should be disabled by default.
39 * It would be nice, when redirecting to another wiki page, to (as
40 * UseModWiki does) add a note to the top of the target page saying
41 * something like "(Redirected from SomeRedirectingPage)".
