Using Moodle Textboxes:  Moodle will automatically disconnect a user who does not have any activity for two hours (this is known as "timing out").  Clicking on a link anywhere in Moodle is considered activity, but typing into a textbox and using the formatting buttons there does not.  Therefore, if you anticipate needing to type into a textbox for two hours or more, please type into a word processing application, and then copy-and-paste the text into the Moodle textbox.  When pasting into Moodle, use the "Paste from Word" button in the textbox toolbar ("Toggle Toolbar" button and then "Paste from Word" button).
