Things to remember in group prayer settings

In thinking about an upcoming time of prayer for the Dove Mountain Church leadership, I thought of the following suggestions of things to remember in group prayer settings:

• Not everyone must pray aloud in order to be united in prayer.
  
• If you pray aloud, pray a-loud enough for everyone in your group to be able to hear you.
  
• Be considerate of time constraints as well as ungodly wordiness (Matt. 6:7), and don't monopolize the time allotted for a given group or prayer topic.
  
• Strive for a balance of sufficiency and brevity in prayers; this is usually what we mean by being "concise."
  
• Though we are praying in groups, our prayers are spoken to God (who knows all things), and not to others; we need not exhaustively explain all of the contextual details of our prayers within them for God to hear and understand.
  
• Meanwhile, while our prayers are spoken to God, they are edifying to the rest of the group; strive to pray in such a way that all may freely say "amen" ("I agree") to your prayers.

Can you think of any others?
