Many organizing committees set aside time and space at the conference for special sessions, which are often planned and organized by select individuals that have been invited to highlight a particular subject or scientific direction.
For example, if you work in computer science and you're specializing in deep learning, you might propose (or be asked) to organize a deep learning special session.
Once your proposal has been accepted, you have to spread the word to interested researchers, issue a call for papers, collect papers, invite an important speaker, and make sure the event runs smoothly.
For those of you that already had this experience, what are your suggestions and advice for organizing a good special session?
For instance, should you get in touch with potential participants before the session is announced?
