The actual post authors are losing the credit for their work in newly created blogs on the net

Hey,

When new blogs are created in my network they get some posts in it (copied from a template blog using “Blog template”)

The problem is that the new site admin is marked as the author of all the posts he got with his new blog and the actual authors are losing the credit for their work.

And I just can’t find the way to get this right (so that original authors are marked as post authors)

Thanks
Ido
