I dont know my Admin User Name/Password

[wackojacko]

Hi all i am new to this forum, i recently purchased leopard 10.5 to upgrade my current version of tiger, only to find that i require an admin password and user name! The problem is i dont have the original boot up discs for my mac and i have no idea how to get around this!! I was wondering if there is any way of installing without the password or username? Any help will be much appreciated
Thanks

You'll need to reset the admin account. Apple provides documentation on their web site to do this, which is an easy search away.
