I have to use the "code" tag to show you. Let me break it down...
This was the original example:
[spoiler]Spoiler text blah blah[/spoiler]
That means you first type this exactly, with the brackets:
Then type whatever it is you want to type...
Then at the end, you type this, with the slash in the brackets:
All UBB code tags work like this. For instance, you use the letter
b to bold, the letter
i to italicize, etc.
[b]bold this[/b]
[i]italicize this[/i]
All the codes are spelled out on the main FAQ page.
I'll create a full thread about UBB Codes when I get some time...
