Possible bug? Browsing author’s posts.

Hi…

I’m having two problems in author-based browsing of a blog.

First, it works if the blog is in the root of the domain, like: https://www.mywebsite.com/author/me/
But it doesn’t work if wordpress is installed and works in a folder, like:
https://www.mywebsite.com/blog/author/me/
I have a 404 error.

The second problem is that wordpress is removing the “.” from the users, so if my username is:
firstname.lastname

The generated link from the template is:
https://www.mywebsite.com/author/firstnamelastname/

Shouldn’t it be:
https://www.mywebsite.com/author/firstname.lastname/

???
