Hello again,

I got it ;)
I setted the blog that will be the main with that option: "Default blog on index.php"

However, the aggregor blog is always accessible here http://mydomainname.com/blog/index.php?blog=1
I would love to get rid of it ;)
Thank for your help,

Why b2e is build that way, I don't know.
I only know, that for me it is what I want.
I have 10 blogs, 10 different subjects.
But my main blog - the agregator - is my news page.
There people can see all the blogs that have updated.

I can understand you don't want that.
But : if you exclude it from the public blog list then It won't show up there.
If that is not enough because you NEVER NEVER want people to be able to make that choise (Why ?) than do the following

Set the blog 1 to 'other blog through stubfile'
pick a filename like welcome.php
Layout that file to be a nice welcomemessage or whatever
or : put a redirection code in that page.

<?php
     $website = "http://www.yoursite.com";
     header("Location: " . $website);
     exit;
?>

Thank for your answer Topanga :)
Nah, you are right. I will try to tame it. However, if I fail, I will use your snippet of code :)
Thank a lot,
