Hello,
my authors are Joomla users having username = email

I found that the link to blogger's page is something like ....../blogger/username

In my case this means that this link shows the email address ( with "-" in place of "@" and "." )

I have to absolutely avoid this.

Is it possible to set the link to blogger's page to ....../blogger/name
where name is the Joomla name field ???
