I've installed a plugin called Quicklink that creates links automatically from keywords in posts. But I'm not exactly sure how to use some of the options and there's no real documentation for them, particularly the 'global search and replace' option.
Anywho, I've added a quick link for VirusDoc's blog, without the global search and replace checked. Let's see if it works:
EDIT: (I removed all the broken links to VirusDoc's blog. :-( )
Hmmm. I guess it works too well. It creates the link and then if the entry is saved again, it creates another link inside the original link (see the text above). I make too many typos and save my entries multiple times, so I think I'll remove it.
OK, they seem to be multimplying even though I removed the Virusdoc entry. This is a test to see if they're still multiplying.
