A little later than planned, but it's done.
3 new features(and some bug fixes) are released in beta:
1. Add email subscriptions to series/all new releases
A new 'Email Notifications' page was added to manage your notifications.On the manga pages you can subscribe yourself to email notifications.
This is a members only feature
2. Strike-Through files the user already downloaded
When a file was already downloaded, it's is striked through, this is a members only feature.
3. Add rss feed for each serie
Each serie now has it's own RSS feed, link to it can be found on the manga pages
Notifications in more detail:
If you're subscribed to a manga, when a new release is added(those that appear on the latest releases page) an email notification is send to your email address.
You can remove the subscription on the manga page or on the 'Email Notifications' page.
On that page there is also a setting for what to do when something new is added, if you always want to recieve a notification, once a day(will put live tomorrow), only for new manga's or don't want any.
Strike-Through files when downloaded:
I've been keeping track of all member downloads for a while now aspreparation for this feature.
Add rss feed for each serie:
This was something that's been on my list since the beginning, it's in now 
If you have feedback, let me know, this is all beta, meaning "didn'textensively test it or think about UI/text", so QA and UAT is up to everyone!
