I've been watching the TWiki fork for the last day with interest. Living with one of the "forkers" makes it more interesting but I also have to watch what is happening because we've used "The Project Formerly known as TWiki" at work for years. I need to make sure there will be an upgrade path for us.
What I hope is that they choose a name for the fork that doesn't turn up with search results about tv shows and puppies. A good example of why you should check trademarks and search engines before naming your project.
