We strongly recommend creating a new Circle for each separate event, school year, or intiative. Keeping media in separate Circles allows for:

• Easier organization and retrieval of specific photos/videos.
• Faster load times (Circles with tens of thousands of photos and videos will take longer to load.)
• Streamlined moderation.

In addition, as each Circle is limited to 65,000 photos or videos, separating things out makes it much less likely your Circle will become maxed out.

For an overview of how to invite the same users to multiple Circles, please see this FAQ.
