Then they can fix the bug and you have bold for unread posts, you click, read, go back to index and the topic will already be showed as read. The unread marker will be disappeared because the user has read the unread posts.
Oh come on, Daniel.
How was this a bug? It worked perfectly for years and it gives the community an indication of what they have not yet read on the community. Removing it basically removes functionality that is (to my mind) critical for the user experience.
What if we decide that we should remove $10 from your license renewal fees because you removed something that we used and need? You wouldn't like that very much (if it was possible for your customers to do), would you?
Not happy with IPS and the response to this criticism. :(
