Google metatags - faq read!!

Ok, heres another strange one for you guys.

Ive read your faq regarding google metatags and have setup my google webmaster account.

As asked to do, ive copied both the metatag name and the code to the appropriate boxes and all is good.
It verified my forum and thats all good.

Only thing is, it verified my www.transmission.darkbb.com address but wouldnt verify www.transmission.ie (which is my main domain name)

for example, the whole point in metatags is to basically see your site on google yeah?

so if i type in transmission.darkbb.com into google, my forum should show up.

but i dont want that, i want my forum to show up under simply www.transmission.ie.

How and why, will google webmaster not allow me to verify my personal domain name, yet it will with mu darkbb domain name??

any help greatly appreciated...
