wpmu blog not indexed

Hello,
I have set up a wpmu blog, 4 months ago and still have only 8 pages indexed on google. I have about 10 other subblogs on this wpmu installation, none of them appear. I have tried everuthing, sitemap, backling on some of my sites, but i don't see anything different.
I did write all the content using UAW, and i changed many sentenses to make my pragraphs unique.
What the hell is going on with this blog ?
My subblogs are all subdomains.
Thanks for any suggestion that may help

try check at copyscape first but i think this isnt your problem. try change a bit again, also your tags, and ping it

regards
