Jubii - Online collaboration. Share files and send email with church staff, elders, etc. Pretty cool UI, but runs SLOWLY.

CircleUp - Ask a question to multiple people and get one, aggregate response. For example, Pastors could ask elders or members to respond to that weeks sermon. Or, pastors can poll members about what topics are of interest right now. Lastly, volunteer coordinators can contact groups of people to see who is available.

Jyngle - Another mobile text messaging service to groups of people. (e.g. Event reminders, invitations, announcements, etc.)

ReQall - A reminder system to help you remember events, to-do's and other things we are all prone to forget. (SImilar to Jott) Call the number and leave a voice mail that the system will send to you in text.
