Hi everybody!
A new PTC, the phd-clix, has been just launched. The first 15000 which will adhere will have for free the upgrade to Premium. At this moment, number of members is just the half, so there are more than 7000 available. I think that this is a good occasion to start a new PTC. This is my referral link:
