CUNY Academic Commons

I tried to invite EFilatova@CityTech.Cuny.Edu to the commons via http://commons.gc.cuny.edu/members/khatchad/invite-anyone/ but received this error:

Some of your invitations were not sent. Please see the errors below and resubmit the failed invitations.
EFilatova@CityTech.Cuny.Edu is not a permitted email address. Please make sure that you have typed the domain name correctly.

These are the instructions of the form:

Enter email addresses below, one per line.
You can only invite people whose email addresses end in one of the following domains: cuny.tv cuny.edu

It would seem that this is a valid email address.

P.S. There may be a case issue here but note: (1) email addresses are not case sensitive and (2) EFilatova@CityTech.Cuny.Edu is in a format typically found in the global address book at City Tech.
