I don't think it is possible in a simple <a href> , but what you can do is link to a page on the server that will open 2 addresses ,that page will also be Java or PHP or ASP , so i think its just better to do it in Zedric's way.
I don't think anyone thought it would be necessary or even usefull when they made the HTML specs. It was a while back you know. When pages where grey with plain text on them basically. So single targets only for the A-tag.
A v6 wouldn't stand a chance against that Z28... it'll break the tires free on dry pavement going straight... AND it's an auto so that's just from punching it, not from dropping the clutch (not that you'd have to in a Z28 with a manual neways).. and right now I've got a v6 camaro so I know what a v6 is like in a muscle car... it SUCKS.
your '99 'stang might stand a chance... if it's a v8 and not a 6.
by the way that car isn't mine... it was my mom's till she sold it... She was gonna give it to me for $4000 cdn but 3 days b4 I was gonna fly down her neighbor offered her $8000 so she sold it to him instead.
