Export Word Doc to PDF with Word for iPad

In the Word document:

• Click the Share (right) icon (the one with a person and a + sign)
• Select "Send Attachment"
• Select "PDF"
• Select "Send a Copy"
• Here I found a few useful options, send to Google Drive (may need to click "More" to enable it), Gmail and "Save to Dropobox", etc.

iPad connects to weak WiFi network

I found one very interesting fact... my work place has a very weak public WiFi.  My iPad normally doesn't able to see and connect to it.  But once I connect a Bluetooth device (either my MacBook Air or even just a bluetooth keyboard), I am able to connect to this WiFi network.
