You will have to sign up first and then tag them either as 'want to read', 'reading' or 'already read' (I think you've already done this? Is this what you mean by bookmarked?)
Updates come in the speaker icon, numbers signify the number of notifications
How do you know when the mangas you bookmarked get updated? I have to click on each and everyone of them to see if they have been updated. Is there a way to get them to have an updated notification next to them? Thanks
