(MIRROR) - Mirror smilies
The Mirror power allows you to mirror (flip horizontally) any smiley that has not been combined with another.
Examples: (biggrin#m) (tongue#m) (hello#m)
Examples that will not work: (biggrin#dhat#m) (xd#cry2#m)
This power can be used in conjunction with invert by using #im or #mi.
Example: (roll#mi) (d#im)
Note: You can use mirrored smilies in your name, messages, or as your main avatar picture, but not as an addition effect to an avatar. For instance, yourpic.png#blood#m wouldn't work.
