Projectfork 4.1 is a project management system designed for Joomla! 2.5 and 3.x, featuring a user-friendly interface and various functionalities such as project milestones, task lists, and user roles. While it offers good design and project management capabilities for small teams, it has limitations, including difficulties with time tracking and task management. Overall, it is well-suited for informal web teams but not recommended for larger, more dynamic project groups.
