i put my uploades to rarely share with freeloades but yet i can't brouse the host when they uoload off me any know why?

on a 2nd ? does any know what hashtree is?

1) you can't browse hosts that are firewalled, this does not mean they don't share.

2)hash trees are identities of parts of your downloads so LW can know if some part of your download is corrupt to redownload that part later. THis is an insurance system called tiger tree hashing TTH working de concert with partial file sharing PFS.

Thank you very much
