"Wait for value to equal value" action in SharePoint Designer 2007

Some of the experiences I've had with building a workflow in SharePoint Designer 2007. If you're working with the "Wait for value to equal value" action and then "Send an email" action, take note of these:

• Make sure outgoing email settings are enabled on the server.
• If the server goes down (or iisreset) while the workflow is paused, then the email will never be sent.
• If using on-edit, subsequent edits to the same list item will not start the workflow again until the first one has finish - there is no queuing attempts to start the same workflow on the same list item, they will be ignored.
