I am new to Xenforo, just migrated my forum from vBulletin. In my old forum I had an item in the top menu that would link to a dynamic page on my website - www.mydomain.com/yyyy/mm/dd/
So, I had a pretty simple plug-in: $my_var = 'http://www.mydomain.com/' . date('Y/m/d') . '/';
Then, just add $my_var to a template and that was it.
How do I do something like that in Xenforo?
