When you make a reply there is an S with a line through it in the gray tool bar at the top of the reply box. This is the spoiler tag.
Just highlight the spoiler material and click the tag. You can add or delete material, just remember that all info you want to hide is between the beginning and end of the tag.
Or you can just type: [/spoiler] after the last word of your spoiler and [spoiler] before the first word.
Thanks so much for the help to you and Arnie and Xay!
