>When writing or translating for the UT-magazine, I used Word (text-only), and turned off the option of using the nicer, rounded quotation marks ("comillas tipográficas" in Spanish). Now, I am wondering, is this necessary? Would the rounded quotation marks cause problems in an HTML text? I think they would cause trouble, but I am not sure.

Yes, better to stick to regular quotes. It is better for me to check it. Thanks for the tip, because I didn't knew you could disable this on Word.
