We have been using Zulip for two years now at Ultimate Bègles (an Ultimate Frisbee association in Bègles (France) of about 100 members). Zulip has been a great choice for many reasons. We were searching for a way to get away from emails and dozens of independent whatsapp groups to share information to our members. What we found with Zulip is a great way to develop our members' sense of belonging to our association. One of the statistics which surprised me the most is that 47% of the 35 231 messages exchanged on Zulip over a two years period are direct messages. As the president of the association, I like many aspects of Zulip: - we can forward emails (received from the federation, from the city, other clubs, other associations, updated schedule of the next tournament, etc.) directly to Zulip channels so that this information is available - there is a phone app (representing 65% of our messages sent) - there is a web app (representing 35% of our messages sent) which is very practical for writing longer posts or more technical content or for a few of our members who do not have a phone - members are free to join public channels and have access to the information posted before they joined - you can do poll using the "/poll" syntax to decide for the date of the next meeting - a discussion can be marked as "solved" - we have a few global channels (Announces, Results) to share global announces or recent results of our teams at tournaments to everyone - we can create private channels to discuss the Administration, the Money, the Coaching decisions privately. As an admin, I like: - message sent to the wrong discussion can me moved to the good one - the title of a subject can be changed (for instance to merge two discussions on the same topic) - we can download a tarball of everything allowing us to download our data and continue with an independent server. - the zulipchat.com server works 100% of the time. It was never down for the last 2 years of usage. As a coach, I like: - players can announce their presence/absence to a training with just a thumbs up/down - we create a new channel for discussing travel/lodging for each tournament, not to spam the other members not going As a user, I like: - members are free to join/quit the public channels of their choice depending on what information they want or don't want to receive - direct messages can be sent to a group of members - while using the web-app, you can copy-paste an image from the pastebin directly in the text - files already uploaded in zulip have a link which you can easily copy to share the same file in another channel/discussion

Quick and convienient space to keep files, conversations, projects together yet being able to find each seperate, add new project members and share them all historical information if needed.

Channels and conversation threads are very useful for compartmentalizing various conversations. The web/desktop interface is pleasant and intuitive. The support and documentation are very effective.
