Please AVOID SWP AT ALL COSTS
I just spent hours trying to fix a simple latex file to make it compatible with my SWP-using coauthor. It's a pain!
I'm not saying you have to learn LaTeX if you don't want to. But you can use Lyx. It will give you the same kind of user interface as SWP, but its more versatile and, most importantly: it's compatible with regular LaTeX.
SWP is an outdated useless mistake that we should forget as soon as possible.
