A lot of times I check messages in my subscribed threads by going into my UserCP. Once I read the replys/messages they don't show up in the UserCP anymore.

But a lot of times after I read replys I don't have time to anser at that moment, and I leave it for later... of course, later I will forget about it.

So, after I read it, and I can't reply at that moment, can I mark it as unread somehow ?
