I always used the Unread link to see what I need to read. The problem with this is that there are always DC posts that I don't want to read, but I have to at least mark and clear them. Is there any simpler way of getting rid of them?

Yes , you will have to visit each DC category , for example Dragon discussion then change watching to ignoring

then reapeate this with every DC section

@Haka-Taka Thanks!
