Marking Read

[BookLover♥]

I know there's a way to mark all posts as read, when you've selected 'Show all unread posts since last visit" or when viewing 'All Unread Topics' ... is there a way to mark a particular part of the boards as read?  I noticed that when I opened "The Books", there's a tab 'Mark Read' - will that affect only "The Books"?  I'm asking because there are a few areas I don't go into, and I'd like to clear them out of the way before I page through all the unread posts.

Also, Is there a way to mark message read if they were posted before a specific date?

I hope that makes sense...

Thanks!

Edited to clarify and ask second question

Yes, individual boards may be "marked read" or the entire forum may be "marked read".

There's no "mark read if posted before date X" feature, though.
