If you keep the option key pressed while selecting Open... Nisus will use the Claris XTND technology if it is installed. And the good news is that there is a XTND Developer package available at ftp.apple.com that includes XTND and filters for MacWrite and MacWrite II. It's in the /dts/mac/tools/xtnd directory, but it's big, about 520K. The XTND file must be in a folder named 'Claris' inside the System Folder, and all translators goes into the 'Claris Translators' folder inside the 'Claris' folder." [This trick works in 3.06; I can't comment on previous versions. I think more translators are available from third parties like DataViz.]
Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
