Question 1 :

Currently I am using CMS 5 EPiServer Manager 2.0.19.3).May I know what is the criteria for CanSubscribeTo return true? thisUser.SubscriptionInfo.CanSubscribeTo(PageReference.Parse(lstPages.SelectedValue))

Scenario:  I have created few page types with property "EPSubscribe" set to true and try to subscribe user to that page using this line. thisUser.SubscriptionInfo.SubscribeTo(PageReference.Parse(lstPages.SelectedValue));

During checking after subscription, however this line always return false. thisUser.SubscriptionInfo.IsSubscribingTo(PageReference.Parse(lstPages.SelectedValue)); I use  CanSubscribeTo() method  to check and found that it also always return false for all my pages.

Question 2:

Which tables that store information on User subscription in the backend database? I would like to check if any records been inserted.

Question 3:

Any sample code for CMS 5 which shows how to do subscription and send alerts for news pages?
