Glenn Fleishman explains a tiny tweak you can make in Lion that enables AirDrop peer-to-peer file exchange to work over local area Ethernet and wireless networks. This enables AirDrop for older Macs that lack the right Wi-Fi chips to work with AirDrop out of the box, and it also adds wired LAN access for even those Macs that do have supported Wi-Fi chips. follow link
Stylin' a Word Comment Balloon
If you work with Word's Comment feature, you may find that the comment-balloon text is too small to work with, or you may just want some variety. To modify the style, choose Format > Style.
