Word.
Mellel, which for some Mac users is the Hebrew/English word processor of choice (and I think it’s supposed to be good for Arabic, too), has just come out with version 2.0. I just downloaded it and haven’t installed it, can’t attest to its exciting new features, but from the release notes it looks like it’ll be easier to use and export, they’ve fixed some bugs, etc. Anyway, seems the company’s offering it for free download here, so rock your funky little multilingual self on out.
Its a 30 day trial. Looks very pretty nonetheless…
