Initially, I created my account in Producteev using my FB account. When I started to personalized my account I decided to set a different email account as my main email address (but keeping the old one in case someone invites me to a network using that one). Since then, the invitation to be part of a new network don't link to my Producteev account. I tried changing the email again but there is a system message stating that the email address it's been used already for another account. This is bing a huge problem on my daily work because I am part of several networks that manage different groups of projects, but now I am being left behind by my team members. Please I need this bug (or whatever it is) to be fixed ASAP.
