Hi there.
I went into the test site for the sole purpose of testing out font sizes on IE 8.0.
I was delighted to see that a font size 3 actually shows as a font size 3, as this hasn't been the case, at least not in the Moodle version our course is currently in.
That being said, I did notice that when I used both Verdana and Arial font faces, there was a difference in sizes 4 and 5 in the editor. However, there was little-to-no difference in those sizes when I exited the editor. When previewing the text as a student would see it, the only difference between these two sizes of fonts was that the size 5 looked a little bolder, not a little bigger.
Is this an issue that may be fixed before 2.0 is released?
Thanks!
