First I'd like to say thanks for this script, it's really useful and has saved me some time. I have noticed a few little issues with it that I thought I should share with you to make the next version even better!
- November and December are spelt incorrectly in the english language file.
- Thursday is also spelt incorrectly in the english language file.
- The title of the A tag for modifying the availability status of dates is always in spanish.
- The variable image_dir in the update_cal.js file isn't actually used (I had to modify this myself).
- It also isn't very clear for less experienced programmers that there are variables that may need modifying in this update_cal.js file.
Hope you don't mind my comments. Once again, this is a great little script! Keep up the good work!
