It sounds all great & grand. Actually the earlier versions of LW had this function. The problem was, it was overloading the network. So rather than having each user searching for a no. of searches, instead each one might have 50, 100 or many more files sending out forced resume searches for resources every few mins. The Gnutella network & also T1 connections & their networks would simply become overloaded with search traffic & slow both their & the Gnutella network down to an appalling speed. It's something the LW programmers have considered & decided it will not happen again. On a brighter side, the Gnutella network is (will be) expanding with some other p2p networks. Thus the resources available will make the availability of files so much more widespread for content & no.

In the meantime, if u do a force resume, make sure u do a search for sources of that file as well to ensure resources will be available for that file when u do go to sleep. Forcing resume is not always a very effective method. At least a search will ensure there's multiple resources & not just the 1st one it can locate (if any at all.)
