Hello, I am looking for an free online organizer to keep up with my calendar, brainstorming, event management, to do lists, etc. It would be great if there was one that allowed each "topic" (i.e., PTO, Work, etc) to be an assigned color. Does anyone use something like this? Which ones do you like? Which ones do you not like? Why? I would appreciate any feedback so that I don't have to try them ALL out.
