A new addition to the family of CRM ‘accelerators’ is the ‘Business Productivity Workflow Tools’.  This is a very useful set of tools that extend the logical functions (actions) that you can perform inside a Workflow rule.

These new custom actions provide additional capabilities around string handling, mathematical functions and HTML hyperlink creation. Once this accelerator is installed workflow designers within Microsoft Dynamics CRM have more flexibility in terms of the processes they can manage through workflows.

This accelerator can be downloaded from the Codeplex site.
