SlideBoom will be down for scheduled maintenance on Saturday April 19th starting from 08:30 GMT. Overall down time may be up to 4 hours. We apologize for inconvenience.

Update (12:30 GMT): Maintenance work has been completed. The web site is back up and running.

We have changed our rules regarding guest users who upload presentations without signing up. Now any presentation that marked as “Published” become available to all SlideBoom visitors. This means that you can upload presentations and share them with anybody in the world without signing up. Tell your friends about it!
