yWriter looks like it should be a powerful program. It even says it can import (if I can figure out how!) works in progress. Unfortunately yWriter is very sparse on documentation, so I have to figure out how things work with no examples... (not, mind that some of the examples that windazed gives for finding and transferring stuff are very good) I don't speak or write geek..... And most geeks don't realize that what they speak and write doesn't translate terribly well to English....
I can't imagine trying to translate geek to Spanish!
