Does Shalach Manos require a Messenger and why?
The Binyan Tzion, questions if you are Yotzei the Mitzva of Mishloach Manos if you bring it yourself, since Mishloach implies that you must send it with a Shaliach. Others like the Eishel Avrohom and Rav Shlomo Kluger hold that you are certainly Yotzei if you bring it personally. Sending it is a leniency that the Anshei Knesses HaGedola allowed. Moreover you can only make a Shaliach for something that you can do yourself. If you can't give Mishloach Manos by yourself you wouldn't be able to make a Shaliach.
