The StacyPlease (@stacyplease) have a single programmer on the team, but between the 6 of them, they have been able to hack through the WordPress code base to get what they want. It’s pretty crazy really. They’re using the builtin WordPress theme editor and using FTP to share files with each other.
Woah. Of all the things people have been using WordPress for, I’ve never heard about something like this before.
