Plug-ins on Member/Forum page templates?

Howdy,

Well, I thought I had a few ideas on how to handle different bugs/lacking elements in EE, but they mostly revolved around my being able to develop a plug-in or module to manipulate the template the plug-in is run on. Piece of cake for the main templates, but not when it comes to forum and member templates.

I was trying a simple plug-in that just output text when called: (partial, sudo code)

Function Helloworld() {
$this->return_value = "Hello world!";
}

Called using:

{exp:helloworld}

Very simple stuff, of course. Well, on the normal templates, it displays “Hello World!” just fine. On the member templates and forum, it shows “{exp:helloworld}”.

Can we run plug-ins on those pages? I know regular EE tags aren’t parsed on them (all the time), but I had hoped this would be doable. Any help?

Thanks!
