I am taking part in the holiday movie challenge and am wondering how to I add the checklist in a spoiler tag so that I dont have to copy and paste in my reserved spot?
thanks in advance

Easy to do, Libby.

Edit your post and put the following in front of/behind your checklist, only without the spaces:

[ spoiler ]CHECKLIST[ /spoiler ]

Or you can use the new spoiler button.

Just highlight the text you want spoilered and click the spoiler button.
