Unfortunately, I can't use rtf2latex2e because it says that DropUNIX "no longer supports the classic environment". I barely know what I'm doing otherwise, besides dropping my .rtf file onto the DropUNIX program.
What else can I use? I don't mind which type of file it is I'm converting to LaTeX (.doc would also be OK, as long as it keeps my formatting).
I am using Mac OS 10.5.8.
Open Office can. Download it.
