Once again, thanks to some help from the guys at the RPF, we now have spoiler tags installed and functioning! In the future, if you have a spoiler, wrap your content in the "spoiler" bbcode tags and the content will be invisible unless the member chooses to click the "show" button... like this:
We would appreciate if members would use the spoiler tag in the future for their spoiler-laden posts!
Big thanks to both Minder Thr33 and exoray (from the RPF) for the suggestions and for pointing us in the right direction! This is not only super cool but very useful!
