I'm having a tough time finding a way to format the text of my wiki. I can change fonts and text size. However, I'm having two issues that have been driving me crazy:

1) When I change text size, color, etc., it doesn't always work. Sometimes, the text is magically resistant to whatever I want to change, and I have to leave it looking funky. This is okay temporarily, but in the long run, I really need to be able to format my text.

2) Usually, when I copy and paste text from Microsoft word, the double spacing stays in tact, and I have an easy-to-read format on the Wiki. However, every so often, the text will copy and paste in tiny, single-spaced lines, very unfriendly for reading. I can't figure out, however, how to format text into double-spaced lines. Am I missed an option, or does it not exist?

I have over 80 pages of text that I'm trying to copy and paste -- so not having this option is quite a problem for me, as I don't want to re-type everything.

Thanks in advance for your help!
