I am a professor at an Ivy League University and a member of ResearchGate for many years. The system now requires "verification". Attempts to verify my institutional affiliation using my university email is not working. the system does not "recognize" the domain thought it is one of the foremost research institutions in the US. I have provided the institution's id number etc. All to no avail. Is there a way to contact ReserachGate technical staff to fix this problem?
