Search Panels?

[wanderer89]

Hi there, first off, if this is in the wrong section, please move, didn't know where to post and it's to do with a skin, so thought this'd be appropriate.

Does anyone know what search panels are, for searching for players, I saw on a forum that someone uses them, I know I've heard of them, just can't remember what they are unfortunately, if anyone knows what they are, and where I can find them I'd be extremely grateful.

Thanks.
