It's so annoying when the OP updates, says she'll be back to update and then you get pages and pages of "marking place!", "come back op!", "ooh what's happened?" etc etc
Can we have the option that when you write a post (like a place marking one) you can tick a box which marks it as a ghost post, then it doesn't actively show without being exposed - ie "there are 8 ghost posts - show all" - so you can still read them if you want but it doesn't interfere with the op's posts, and you don't have to scroll through hundreds of place-marking to find the op's updates?
adding to the watch-list doesn't work in the same way as place marking!
