Can you display HTML in SuccessNotification?

I wanted to put a "link" in the success message so I could click it after it's successful. But when I do <a> tags it displays the tags and not a link.

Thanks!

Which success message are you talking about?
After the customer completes his order?

If so, you can open this view:
/Views/Checkout/Completed.cshtml

...and add your link there..maybe just before the Thank You button...

Just in a Plugin Controller I have. I use

SuccessNotification("Done");

I was wanting to have the option to be like

SuccessNotification("<a href='thislink'>Successfully added XYZ</a>");

then I could click it and go to that product in the products catalog. It's not dire, just a thought.
