Can you please verify my robots.txt for wordpress

Question

I am a newb in writing this and since this is dangerous stuff to fidlle with (if you are not sure what you are doing) can you please verify it?

I use wordpress multisite, this is why I chose to allow blogs.dir

I want only my posts and categories indexed. That's it:)

The file robots.txt doesn't exclude all the search engines to crawl your site... Most search engines crawl the hole site without taking the robots.txt file in consideration.

I think that the best way is to use meta tags in the theme of the blogs.

Use the next meta tags for post and categories template files:

<meta name="robots" content="index, follow" /> 
<meta name="googlebot" content="index, follow" />

Use this meta tags for the rest of the template files

<meta name="robots" content="noindex, nofollow, noarchive" />
<meta name="googlebot" content="noindex, nofollow, noarchive" />
