Question from the customizing inept :-)

I've been using Sunday Morning and I guess the font update has occurred, because I'm being blinded by the new *HUGE* font. But if I used the customization listed above, I'll be creating an accessibility issue for people viewing my journal, because they won't be able to resize the font?

So what's the style of this journal, because this font looks like a good size for me. ...unless this one is going to get changed to.
