I added a spoiler tag so that people who haven't solved a cipher yet won't see the solution unless they wish to.

You can either use the SP button among the tag buttons, or simply type:

Code: [Select]

[spoiler]Solution here.[/spoiler]

[Stun90]

What SP button? Type CODE: where?  Please explain. Thanks.

You don't need to type "code:", just surround the solution with the bracketed spoiler tags. I was just trying to show what to type without the tags becoming obscured. As for the SP button, it's the next to last one on the right of all the other buttons above the smileys when you're typing a new post.
