At the services, there is a canopy labeled Next Steps. People there can help you get plugged in (they also usally have a gift bag for non members with some Summit swag). The membership class is called Starting Point and is usually held every couple of weeks. However, the best ways to meet people at Summit are small groups and serving. You can start attending a small group even if you're not a member; they can get you plugged into one at the Next Steps tent. Don't be afraid to visit a few different small groups to find your niche, it can be a little awkward at first but its a great way to build lifelong friends and community in a big church.
When you get to the next steps place, be sure to tell the representative there that you are looking for a small group. Being in a small group makes being at a church like ours that is huge more manageable. You won't be lost in a crowd, and a small group can be like a family or support system. If you are away from your home or family, this can be important. The representative will take down your information and you will be referred to one or more small groups to consider that will be geographically close to your home. The leaders of the groups will also be notified so they will know you might be contacting them.
Thomas R, spot on
