We've published some new requested functionality in Beta format - the My Account page now has functionality to allow you to print invoices to get reimbursed for the DynDeveloper.com expense.
It should be fairly straight forward. If you see any issues please note them on this thread and we'll fix them right away.
Alternatively, you can send an email to support@dyndeveloper.com if the info is private.
Thanks, and happy testing!
