//  -The old "Mailto 2 Webmail" was taking 10+ seconds to work its magic on an average page, on my computer.
// For large forums, it'd take several minutes. Well, now it takes under 2 seconds.
// ...
// ...
// I know, I need to upgrade my system. :P
//
// Well, maybe this more efficient version will be helpful to someone.
