A method of facilitating the organization and presentation of video e-mails containing embedded video provides a repository for distinguishing video e-mails from regular e-mails, displays the contents of the repository, and, in response to their selection, streams embedded videos from within the e-mail client where the body of an e-mail is usually displayed. In one embodiment, an emissions treatment system for an exhaust stream is provided having a catalyst comprising silver on a particulate alumina support, the silver having a diameter of less than about 20 nm. If an output port is available, the resource management mechanism then reserves the requested output port. The position sensor system is mounted within at least one of the inner spaces.
