We have a product on my website which we don’t offer anymore and that product has been replaced by a new product. Now the problem is that there are forum posts of the past mentioning that product and when new users browser through the forum they see those posts mentioning the product but they don’t find the product anywhere on the website.

Is there any way I can replace the name of the product with the name of the new product instead of having to edit tens of posts.

Also I’d like to know is there any way to auto convert certain text in the forum into hyperlinks.

For example, in phbb, the admin can set certain terms in such a way that whenever the term is mentioned it gets converted into a hyperlink. For example, if anyone mentions say an ipod in the forum, that term gets automatically hyperlinked to the thread to which it has been set. Let me know if you guys understood the question.
