I'm curious as to what software you designers are using to create your TT fonts. I have a disk for Fontographer 4.1 for Windows that I never installed and now it appears to be corrupted. Since I have the serial should I try to hunt down another copy or look for a different software?

If you bought the program you should be able to get a replacement disk.
Otherwise one can create fonts in CorelDraw. There are also a couple of freeware programs out there. Google is your friend.

If you can't get a replacement for your disk you may want to try Font Creator or Altsoft's FTMaster. Both are Windows programs. Both have trial versions. Font Creator's trial is fully functional, FTMaster throws in 'funny' bits and is therefore more a working demo.
