Greetings @sweet-salty, permit me share more about curators to let you have a better understanding of what curators are all about. Each month, the steemit team launch an opening for individual users to form a team of two or three and even as a single applicants to work as community curators for the said month. Those meet up with the application requirements are selected and given the opportunity to use steemcurators 03-09 accounts, with Steemcurator03 having SP of 1million and the rest of the accounts having 700,000SP each to support different users’ content across the platform.

For the active communities, you can go to explore communities and go through and make your choice. Each community has its goals and rules.
