Different links for different forums.

[mpage]

Anyone have an idea how I might go about doing this:

I want a link (under the posts/signature) to point to a particular place, but I need this link to be different for paricular sub forums

How might I go about adding these links?

(rather like targted ads, for example, under the cars forums, each post/thread might point to my cars blog, and under my train section, each post/thread will point to my train blog...etc)

Eg, on this thread, if forum title contains "General vBulletin Discussions" show "this" link under the posts

It looks like this is not possible, and no one has created a plug-in.

I write in php/java, so can some one direct me to the knowledge base documents for writing vbulletin plug-in?
