Anyone using Comcast email after cancellation?

I've been told that I can retain my comcast.net addresses (primary and all secondary) even after I cancel all Comcast services, as long as I do the following:

In regards to your Comcast email account. You can keep the email as long as you do the following 2 steps. Log into your Comcast email account within 90 days before disconnecting your service, and you must access your Comcast email at least once every 12 months.

Is there anyone out there who is currently doing this and/or know anyone who is?  If so, are there any restrictions/limitations on usage of the web portal, 3rd party clients like Outlook, etc.?  Thanks.
