This is real cool for people who use notepad to write down any info on a day to day basis... In Notepad

• Create a blank text file with .LOG as the first line of the file, followed by a carriage return.
• Double-click the file to open it and notice that Notepad appends the current date and time to the end of the file and places the cursor on the line after.
• Type your notes and then save and close the file.
