I'm a complete beginner (which I freely admit), and when I go into the "Search Templates", select the style I'm trying to fix, then paste the above text, the following happens:

1. It takes me to the style manager options - and asks me to select which style I want to modify.
2. Then it shows me the template "header - header include - footer" - NONE of which has any of those words in the html boxes.

Where can I find those words IN PLAIN LANGUAGE, so I can modify them?

EDIT: I think I'm on to something, just by not using search, I came across the forum rules, and this bit of code:

<vb:comment> regular forum rules </vb:comment>
{vb:rawphrase forum_rules_registration, {vb:raw vboptions.forumhome}, {vb:raw session.sessionurl_q}}
{vb:rawphrase forum_rules_description, {vb:raw vboptions.bbtitle}}
<vb:comment> regular forum rules </vb:comment>
</div>

Now - I'm still a complete beginner - so where in this snippet of code do I find the file which contains the actual text?
