Not sure it is the right forum but according descriptions I haven't found better place.
I'm facing an issue with the send email feature for invitations to be sent. If there is a comma in the "first name" field ( and most likely last name field too ) sending email fails for those recepients. I can live with this as I replaced by - sign, but I guess there is a limitation somewhere.
If it could be fixed in further release... could be nice
