Socialtext by Socialtext

Socialtext is a hosted wiki service for personal and professional use. The product features account management, controlled access, and secure access to an online collaborative workspace. Socialtext's wiki software integrates with external web services for automatic updates. Users can submit updates via e-mail and instant message, looping a persisted knowledge storage solution into their workflow. Small groups of users can use the service for free with no support. Larger groups pay Socialtext for access, support, and increased storage.
