i copied the code in post number 7 and now i don't have show and hide but "mostar" and "Ocultar"

Sorry again... Now it's all in English... (i forgot to change that words because my forum it's in spanish :P)

ElForro, thank you so much! awesome!

Nice! I just installed!

To keep the spoiler out of the hover, I'm advising my users to have at least three lines of text before putting in the spoiler (may it be words, dashes or whatever).

Thanks, I've installed this! :)

Installed, love it :)

Installed, thanks.

Was there ever a way to make it not show in thread preview?

GSX-Racing... I really don't know... But if someone does please help here so we can make this a better spoiler tag =)

Yeah, that would be sweet.

I tried just putting a period on the first three lines but that didn't work. I guess you have to put the 150 characters (or whatever thread preview is set to) in order to hid the spoiler info.

The problem with previous versions of this is it didn't work if Firefox, does this work with all browsers?
