Hiders can either be awesome, or a nuisance. A few times I've seen someone use so many Hiders that I wondered, [i]"hell, why not place the entire CS in a hider so I don't have to spend 10 minutes finding out which one of your 20 hiders the info is contained within."[/i]

Generally I will avoid them as they often mean people skip out on some details due to thinking the contents is less important.

If I do use them, I mostly use the (hider=) so they appear simple.

[hider=]
