Robin Good: If you are tempted to use a collaborative wiki, to let your team, colleagues or fans participate and contribute to a common project, but have been reluctant to use one because of the difficulty of getting on-board people who were not familiar with this technology, your wait is over.

HackPad is a very user-friendly wiki platform which allows you to co-work and co-edit text documents containing images and videos with maximum ease and least effort.

Key features include:

- Authorship colors show you who wrote what.
Easy sharing.

- Invite by name or email, or just share the URL.

- Linking immediacy. Just type '@' and you're creating links or new pages.

- Changes are emailed to everyone. Email reply to update pages quickly.

- Keep track of all your plans using task lists.

- Find pages instantly from your desktop with the taskbar app for OSX.

- Private instance. Safe and secure.

- Choose your own address:

- Import your existing MediaWiki or Google Sites Wiki.

- Administrative tools. 24/7 support.
