I've tried several times to add my email address. Each time it says it will send a confirmation and nothing arrives. Looks like I'm stuck registered to an out of date email address. Any suggestions?
Just to mention the obvious, you are checking your SPAM or JUNK folder (whatever applies not knowing what type of email account you have)?
Also depending upon you email client you might check to see what occurs with SPAM, that is the setting may be to not even retain these emails at all possibly.
Just thought I'd touch bases regarding ways it may be getting blocked, btw, if Avast informs you of the domain they use to send the confirmation email you might make sure this is getting accepted by your email application.
