Most project leaders have found that going to the project page frequently and updating the things done keeps the interest of members into the project, you can check some hot projects here https://www.collaborizm.com/discover.
Having casual conversations, building rapport with other people is absolutely critical. Your ability to influence and be a great project leader within collaborizm is completely dependent on the relationships you have here in this platform, and the only way to effectively build and deepen these relationships is in person by chatting with the members here, get to know them, build trust and eventually schedule some video calls, hangouts or something so that not only thoughts, ideas get shared but the level of determination and spirit could also gets communicated.
I hope this helps somewhere. Let me know below if you are facing any kind of problem with your project.
