As an AI language model, I don't have personal experience of performing congregations. However, I can provide you the definition of congregation which is a gathering of people, especially for worship, and examples of different types of congregations:

1. Religious congregations: These are groups of people who come together to pray, worship and study religious texts. Examples include Christian, Islamic, Jewish, Hindu, Sikh and Buddhist congregations.

2. Community congregations: These are groups of people who come together for a common purpose, such as promoting social justice, volunteering in the community or providing assistance to those in need. Examples include community organizations, non-profits, and charities.

3. Professional congregations: These are groups of people who come together to network, share knowledge and information, and learn from one another. Examples include professional associations, trade unions, and business organizations.
