The web is full of tools for collaborative project management, and generally they work quite well, but if you need to take it a step further, sooner or later you'll have to contend with solutions like Basecamp or Slack, both proprietary and costly. Another option is to create a wiki, but its format tends to be quite restrictive. If you prefer something more flexible, free, and don't mind a bit of learning along the way, perhaps Agorakit is what you're looking for.
If you want to start a project aimed at recording large amounts of information and plan for other people to participate, the first resource on the list is a wiki. Everyone can collaborate with texts, images, and links, reaching a fairly high level of complexity. The problem with any wiki is that it runs the risk of becoming an administrative nightmare, and vandalism is common. Then we find more “professional” tools like Basecamp and Slack, but Basecamp costs a small fortune, and Slack's free mode has several limitations. If the project is small enough, another possibility is to create a simple Facebook group, but today I'd like to talk about an alternative called Agorakit.
The developers of Agorakit describe their platform as designed for civil initiatives, although personally I haven't noticed anything that prevents more private use. Agorakit combines the functions of a forum, calendar, file manager, mapping, and email notifier. There is no limit on the number of groups that can be created under each project (those marked as private access will be subject to approval), the calendar is fully collaborative, easily identifying events of each group, the mapping section allows us to locate everything via geolocation, and the repository greatly simplifies the management of links and files. A common thing is to end up bombarded with emails, but Agorakit provides precise controls for receiving notifications.
Agorakit is open source, its code is available on GitHub, and anyone can modify it as they wish. If you're not sure Agorakit is the ideal tool for you, don't worry: the online demo will help clear up doubts, including its installation. Unfortunately, it doesn't reduce to a double click, and you'll need a hosting service with basic tools.
