Papik81 on "[Plugin: ALO EasyMail Newsletter] User can subscribe to no groups"

Unlogged user can subscribe via e-mail and if he or she chooses no groups, the e-mail is saved too, but no newsletters can be send (because for no group there is no e-mail) but cannot use his or her e-mail to subscribe again.
I'm missing error message "Please select a group you'd like to subscribe to". Or I am doing something wrong?
