Understanding how to preregister variables.

[Seductor]

Hi there,

I'm trying to understand how to preregister varaibles. In this example, I'm using FORUMHOME. This is my plugin:


And this is my template:


Nothing is being displayed. Why?

Another question. I have read this tutorial, indeed:
https://vborg.vbsupport.ru/showthread.php?t=228078

But I don't understand wht I need to use vB_Template::create to register a variable in a existing template. Does vB_Template::create create a new template and will I find it in my templates list? Is there any way to register a variable without creating and rendering a template?

Thanks.
