Where is the interface to access this information including the email address entered?
Enable commentsModeration ="true" through Events provider section of your web.config file.
|<add name="Events" allowComments="true" urlRewriteFormat="[Publication_Date]/[Title].aspx" urlDateTimeFormat="yy-MM-dd" urlWhitespaceChar="_" visible="False" defaultMetaField="Title" securityProviderName="" allowVersioning="True" applicationName="/Events" versioningProviderName="" commentsModeration="true" connectionStringName="GenericContentConnection" type="Telerik.Events.Data.DefaultEventsProvider, Telerik.Events.Data"/>
This will give you opportunity to manage users comments.
Is it possible to turn off the ability to post comments?
To turn on/off comments, open EventsView control designer edit mode, go to Advanced tab, find Comments category. There is a dropdown control from where you can manage comments. You should also set allowComments="true" or set false value in the web.config <providers> section for the desired provider ( Events, News, GenericContent and so on);
Let us know if there is anything else that we can do for you.
All the best,
the Telerik team
