MFJ, there is a difference between MSPA membership (which expires) and certification (which does not expire).
To the OP: I have been MSPA gold certified since 2003. Back then they had workshops for gold certification, which was worthwhile in terms of learning and networking because many company reps attended. Nowadays, the workshops have nothing to do with certification and gold certification is obtained online, which is much less valuable, in my opinion. Back when I got my gold certification I do think it helped me get advantages such as first dibs on shops since some companies would send out blast emails ONLY to gold certified shoppers first, and after we took what we wanted the rest of the shops were released to non-certified shoppers. That doesn't happen much anymore. I don't think you need to worry about getting your certification, and as wales mentioned, some (Sassie) websites are having difficulty with recognizing the certification numbers and the MSCs have been working on trying to get the numbers entered manually for shoppers. Some of them take a very long time doing so, which makes me think that it isn't that important to them anymore. What is important is that you complete and submit your shops in a timely manner, try not to cancel and never just flake on a shop, pay attention to guidelines, and submit well-written shops.
