I think it would be easier to check an all of one's discussions in PM if every user could check easily if someone replied to an node of his/her. This could be done for example by adding a new colum in the usres home-node. So you can tell at one glance which of your nodes have been replied to.
The second idea that came to me whie I was taking a shower this morning is, that it would be cool if you could edit a node offline and run a script that will pot it for you on PM. I have been searching for modules that will allow this easily but I found nothing. Is it possible at all to login to pm via script add a node and logout again? Some script like a newsgroup program for PM would be cool t. Is there anything like it available. My data minig did not bring any results (as said above).

P.S.:Of course this is subject to discussion so don't take this node as one from the make-vroom-do-more-work-for-months dept. :-)
