Thread:Project:Support desk/Display template on every page/reply (5)

Ahh, what you want is possible. It's all possible.

No need for an extension or for an additional article object of its own. Instead, check Manual:Hooks for a hook to use; especially those in the section "Skin" might be interesting. Then add your HTML code from inside the according hook.

What I have not fully understood, where you want your content to appear. Is it at the very top of the page, there where it also says "Create account", "Log in" or "My contributions"? In that case I would pick the hook "PersonalUrls".
