Found 1 small bug (?)
Says you can use html .... But it may not be compatible with XenForo linking
Code:<a href="{xen:link 'login'}" >login here</a>
When clicked on the notice it

Yeah. Sorry about that. It's actually as designed.
It's because the notice HTML is rendered from the JavaScript rather than a template.
You will have to just use good old <a href="login">login here<\a>
