Fictionpress's default format is rather hard to read. Small text spread extremely wide is nearly the opposite of ideal.
However, there is a way to improve that. If you look at the upper right hand of the page, there are a bunch of buttons.
If you mouse over those buttons, your browser should display tooltips telling you what each button does.
Basically, those buttons allow you to adjust the font size, which font is used, the width of the text column, the spacing of the lines, and many other things.
If everyone knew this, fictionpress would be a much more appealing option.
Anyway, here's my fictionpress account, which has a variety of old stories that weren't very good.
