fossil is great, and I wish more companies used it. It's so simple, has everything you need, documentation, bugs, email alerts, chat, a forum, a wiki. It's all there. Having to go to jira to manage something, confluence for something else, git for source code and bug tracking, it's all a mess, when you can use something like fossil. Yet all I hear when I mention fossil is "never heard of it, not using some toy project, sticking to what I know".
