Now members can subscribe to get new post notifications via email or simply track topics without emails.
Checks are done to make sure members are not emailed more than once per minute for the same topic and not until they have read the topic again.
If you have an active site, it is important to consider that some ISPs may decide to block your forum's emails simply based on the volume of emails when you use a plugin like this. Make sure your website has proper SPF, Sender ID and DomainKeys to help delay blocking but if it's a very large site you'll probably have to pay a whitelisting service to stop blocks eventually.
