I've just updated the spoiler function,
it looks much better (i think) with the border!
But there is a little problem, when we show the text all nearing text are pushed away, just try:
[spoiler]i put my avatar to really see what happened!

[/spoiler]
If it disturbs you i can change it back or i can make the border to fit the final size of the spoiler!
That is your choice?... I would make an average of the answers!
