I just recently found out that I passed the WF 3.5 beta exam (well, actually I passed it some time ago but it took Prometric, the world's worst test provider, a while to figure out how to send the score to Microsoft). So here is my new logo:
Since they wrap a lot of the words, you really need to spell it out:
Microsoft Certified Technology Specialist - .NET Framework 3.5, Windows Workflow Foundation Applications
I think that is my longest certification title to date. The Windows Mobile 5.0 is a close second.
BTW - I also found out that I didn't pass the WPF or the WCF exams so I'll have to retake the real ones at some point.
