Actually [url=http://www.w3.org/TR/html401/struct/links.html]all links are anchors[/url]. I'm guessing that's why the tag is "a" instead of "l". Anyway if I understand correctly, what you want to do is link to a specific post every time you use a specific keyword. IF that's the case then check out the [url=http://plugins.b2evolution.net/index.php/2007/01/06/acrolink_plugin]AcroLink plugin[/url]. As long as your keyword doesn't have punctuation in it (like for example doesn't does) it'll do what you want. (be careful though: the person who wrote it is an idiot)

That looks perfect! And I've received quite a bit of help from that guy and I don't appreciate you calling him an idiot. However, I'll reserve judgement until I try the plug-in out...

Did you end up using acrolink?
How is it going? Are you satisfied? Would you recommend it?
