Because old press is reluctant (to say the least) to link to other websites either blogs or not, some people prefer to add a rel=”nofollow” tag when linking to those sources.
Because of that I decided to create this Plugin. It’s based on the Wikipedia nofollow plugin and now allows you to add/remove/edit domains from a blacklist. All domains on the list will be rel nofollowed.
Note: If you add for example wikipedia.org every subdomain from wikipedia will be rel nofollowed, but if you add en.wikipedia.org then only the subdomain will be rel nofollowed.
It’s my first plugin and is far from perfect but hope you like it!
EDIT 25/8/2007: Just did a minor edit on the plugin. The plugin was also rel nofollowing links on comments which would probably interfere with other plugins which do nonofollow on comments. You can download the edited version or just erase the last line of code in wordpress’s integrated plugin editor.
