Mariette,
Hi. Alex is working on updating the documentation as I type, at the very latest he should have something updated by the end of the week. I can explain any functionality questions you have.
Two major features within opt in email categories
* Sort order - this really should have been there before, this sets the order the cateogires appear in for the user-facing side.
* Distribution Security Role - This allows you to set a security role that is allowed to distribute newsletters for this category. This allows you to offer the Advanced Newsletter module to multiple users and they would only have rights to distribute emails to certain categories. Host users will automatically be able to distribute to all portals and Admin users are able to distribute to all categories within the portal.
Within Advanced Newsletters:
The major features here are the ability to schedule newsletters. Just make sure you set a total amount to send per schedule. What this does:
* Lets say you have the scheduler process run every hour and you distribute a newsletter to 5000 subscribers. If the total amount to send per schedule is 1000 then it would distribute the email/newsletter to 1000 subscribers each hour and would finally complete at five hours. This is useful if you have any restrictions on your server or would like to only send out a certain amount at a time. We have tested this distributing to over 20,000 email address's without any major performance issues!
* The other import items within scheduling are the ability to log different items during distribution. Keep in mind that logging would slow things down and add to the log file but it can be useful.
* Use 'Test Mode' and 'Test Email' for testing. This feature would generate each email for the subscriber but would send to the test email instead of the actual subscriber. This is useful if you are wanting to see exactly the email they would receive including the opt out links etc.
