Dungeon Master Forum

There are a few threads (Episode 3 and confluxII and maybe soon PaulH new dungeon discussion),
where there are risks of spoilers.
There are some ways to cope with that. The first one is: Mark the thread with "!!!SPOILERS INSIDE"" or similar.
The second one I know of is: Either make the font a very small size, so the probable reader has to copy and paste it
into a texteditor and increase the font size in order to read it, or just leave some space between,
so the forum user has to scroll down.

I wonder if there is not a more elegant way.

Since there is no possibility to change the background colour here,
I have the following suggestion:
Of course this will be work and it most likely will finally be up to Gambit to decide if, how and when, if .

Here it comes:
On a forum there was the possibility to put a box into your post.
(much like the quote box here)

This box was only readable if you would select the text written in it.
(having the same background- and font colour)

Do you get the idea?
Is that something this forum badly needs/ You would use?
Is there an other way, which is even better or do you like it the way it is?

There is another thread with this suggestion, but this is still a good idea...

Please read the forums before creating duplicate threads, we already have a thread for this suggestion. Thanks.
