Conference
From ReformedWiki.org, the wiki for Reformed Christianity
A conference is a kind of an event, one that usually involves keynote speakers who deliver messages that are based on a theme or a shared set of beliefs or values. Conferences can span from one to several days, and can be one-time events or held on a reoccurring basis (such as annually or biennially). Conferences are usually hosted by churches or other ministry-related organizations. Conferences are usually attended by members of the public, although some conferences are more specifically geared towards certain audiences (such as Pastors/Elders).
