I was wondering, does this site have any kind of spoiler tag functionality, and if not, can something like that be implemented?
This isn't a big deal with a lot of themes, but in discussions of incredibly story-driven themes like Ninjago or Chima (or licensed themes based on recently-released movies and television shows) I think it'd make a BIG difference.
There are lots of different kinds of spoiler tags. Some sites make text white so you have to highlight it to read it. I tried using HTML tags to change the text color to white so you'd have to highlight it to see the spoilery bits. No luck — the CSS overrides that.
Other sites like the LEGO Message Boards, BZPower, or Eurobricks have specific spoiler tags that "collapse" around any text you include in them and you have to click a button to "expand" the text if you you want to read it. I don't know how much the possibilities depend on the forum software, though — Brickset forums run on much different software than the IP.Board software that forums like BZPower and Eurobricks use, and I believe their software has built-in plugins to handle spoiler tags and things like that.
If there IS already some kind of spoiler tag functionality in the Brickset forums, there should be a place you can look up the tags for that kind of thing. I searched for something like that but had no luck.
