MVP membership

Good day, 

I would like to become a MVP - but I remember in the past you need to be sponsored and be active in the technical Microsoft forums ? I've got a MCSE. MSCD, MCDBA and MCT certifications under my belt. But not sure what the next step is ? I also my internship in the UK with the SRG team in Reading.... (and met the developer who designed and codes the old 'robocopy' console app :)

Thanks and regards,

Pieter Claassens
