Oops I did not know that, see my last post, that's actually what I use.
Which means I'll have to redo how I do admin notices, back to the drawing
board as to how to do this simply without 4 lines of code and a new function
with lots of redundant code, which idk if that will be possible short of
some core implementation.

I'm working on a support ticket plugin and I'm looking for users to test and
provide feedback on it.  Will bribe anyone who helps with a generous
discount on the final product.  Email me off-list if interested.
