Prodigy/Internet email details are still fuzzy, but Jeff Needleman <email@example.com> said that the software for Macs to receive Internet email works fine, but the software for sending only works for DOS machines. So, Prodigy has to decide if it will allow one-way Internet access for Macintosh users, at least until a version of the software that can send Internet email appears on the Mac side of things. Why do we suspect this will slow the entire process down a good bit?
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
