When a normal member goes to make a and adds gremlins or stylized text (colored, bold, different font, etc) when they press preview post one of two things will happen depending on which markup setting they have selected:

With “using UBBCode” the gremlins/stylizations appear.
With “using HTML” or “using HTML and UBBCode” the gremlins/stylizations don’t appear.

The strange thing is that for admins it works differently:

With “using UBBCode” or “using HTML and UBBCode” the gremlins/stylizations appear.
With “using HTML” the gremlins/stylizations don’t appear.

So what I want to know is how to get the normal users preview to work like the admins.
