Hi {{ name }}, One of the big things that's different about Zulip is the idea of "streams" and "topics". While they take a little getting used to, once you get the hang of them, they're really powerful. Some tips: * Would you make a mailing list for something? If so, it should probably be a stream. * Topics, on the other hand, are a lot more like subject lines - or conversations in Gmail * The big difference: keep topics super-short and lightweight. One or two words will do it. * Good topics: jQuery, Bug 345, lunch, zulip * Bad topics: "What do people think of this?" "Where should we go to lunch?"
