Here is a direct quote from Aaron's press release of 9/22/00
"Some of you have asked about Map Editors and Scenarios editors. They don't exist yet, but they will. Probably not in time for the full release, but they will be made available soon after the release for free to all owners of SE4."
nmoppa and Pathy, you both sounded like you thought I was imagining things
Not that I'm unhappy with Aaron or Shrapnel, I just thought it was reasonable to ask a polite question, given that, (as you can see from the quote above), we were told it would be along "soon after the release".
