Consider the following scenario. You create a survey, and then you add a workflow to the survey in Microsoft Windows SharePoint Services 3.0. Then, you connect to the survey and respond to it. Finally, you view the response that you submitted, and then you try to start a workflow from the response. To do this, you click the arrow next to the response, click Workflows, click the workflow that you added, type your user name in the Reviewers box, and then click Start. However, the workflow does not start. Instead, the status of the workflow appears as Failed to Start.

This issue occurs because starting a workflow from a survey response is not supported in Windows SharePoint Services 3.0. Although the Workflows option appears when you click the arrow next to a survey response, you cannot start a workflow from a survey response.

Microsoft recently released a new Silverlight 4 based facebook client for both Windows and Mac OS X. Scott Guthrie originally demonstrated this Silverlight client for Facebook during his PDC 2009 keynote late last year.

Based on customer requests for more robust compliance features, Microsoft has improved the validation capabilities of lists and libraries. Validation is now supported at both list and item levels.

For instance, a list owner can configure a validation to disallow the start date of an event item (stored in one column) to be after the end date of the event (stored in another column). If a user enters a start date that is later than the specified end date they will be presented with an error message when he or she attempts to save the item.

In another example, people can specify a column in a list as unique so that a contact list may not contain two entries with the same email address.

The activity feed in SharePoint 2010 is very interesting. It is a way to see and read what your co-workers are doing. Most of your actions in SP2010 will end up in the activity feed.

But what about your actions and updates outside the organisation? Like twitter?

Stef van Hooijdonk created a class that will import your twitter updates ( through your public timeline rss feed ) and will post those updates to your activityfeed. Form more information and download; click here...
