can we copy users from one blog to another

[falguni1]

hi,
I use wordpress. I have registered users to comment on one blog.
I want these users on my other blog where they are not registered.
can I use these same user on my another blog to comment as registered users.
I means I want to share the registered users on both blogs. I dont want them to register again.

You would have to import the users into the other blog's database for them to be registered without making them actually register.

If you just want to copy once its not big deal. You just have to import couple of tables.
If you want new users to do the same thing then you have to make some changes in WP so that it uses on db table for both the blogs. Or you can try OPENID plugin. This is good if you have many blogs
