Sometimes we want to share some information on the forums but we are not sure everyone will want to read it. For example, you might have found Sylvan Glade and want to share how to access it, but other players may prefer not to read any hints and find it themselves. Time to use spoiler tags!
Spoiler tags hide the content you place inside, giving other Simmers the option to click to reveal the content.
Another good example on when to use spoilers could be when you want to post a lot of pictures in a single post. It's better if you post 2-3, and then hide the others inside a spoiler tag - that way who wants to check those pictures will be able to do so, but the topic won't be soooo long

Spoilers look like this:
This text is hidden by default
How can you insert your own spoilers?
While writing your comment,
select the text and/or images you want to hide inside the spoiler and then use the following option:

Nope can't figure it out
LOL, I must have missed the word highlight then click on Spoiler. Thank you!
It's me, not you, lol, I didn't understand select. I'm a noob when it comes to website tricks.
It was only recently that someone shared the secret of how to make the tags here.
Awesome! Thanks, @EA_Mai

Thank you so much for pointing out that if someone is planning on posting a lot of images they should put most of them in a spoiler. There are a few popular threads on here I would love to look at, but I avoid them because the posters on those threads don't use spoilers. Tons of images in a post make it load way too slow. Especially for those who don't have very fast internet connections and/or very much RAM. Hopefully they'll see this thread and start doing it now as suggested. Thanks again and...
interesting idea!:) I am a moderator on some internet forum, and I have always been sceptical because possibility of hiding inappropriate content inside spoilers and added work for staff to check every spoiler, but here I see that it can work nicely, especially when thread contain many images. How about introducing a button for opening every spoiler inside of a post/thread? Just an idea.
Hey
Did it work
