Why take functionality away?

I recently received an evite at an email address that evite was not informed about, so I went to add it to my profile as I had done multiple times in the past. Couldn't find the option, so I checked the FAQ:

How can I add/edit the email addresses attached to my Evite account?
Currently, you are not able to add, merge, or edit your email attached to your Evite account. We are in the process of improving this feature to ensure that it functions properly. Please check back as it will be returning soon!

What? Why? So aggrevating. Why do they tease me so? Oh evite, how far you have fallen...
