Is there an easy way to increase display / font? My global settings thru Internet Explorer leave the screen size a little small for my comfort?

I figured out how to increase the font size on MY posts - I'm trying to reset the screen size for everything else.

Second Question: How can I enable TABS in my posts? Text that I have aligned using the TAB key does not display as intended. Even when I use repeated hard SPACEs, it doesn't display properly?

Do we have a tutorial available? I really like this format; tryig to shorten the learning curve.

Thanks. Appreciate any and all tips.
