How does one abort the previous request unless a queue is being kept track of? Also, there could have been a few other requests made between the first save and the second save. Its definitely possible I'm just not understanding how XMLHTTPRequest objects work - please do explain if you think that is the case.

Also - I'm not necessarily using XMLHTTPRequest, I'm leaning towards dynamic scripting as my site will need this widget to run across several different subdomains - dynamic scripting doesn't have a lot of the nice status functionality that XMLHTTPRequest does...

Okay, here's an alternate method.

 When a user needs to save their note
  If the note is already saving
   Set note.saveAgain = true
  else
   Start the process of saving the note
 
 When the note has saved
  If note.saveAgain == true
   Set note.saveAgain = false
   Start the process of saving the note again

That doesn't require a queue. It also only saves the most up to date version.

Cool.

Thanks again.

I can has karma now?

Edit: How dare I ask to be compensated for my time. I should be ashamed of myself.

Thanks!
