I've just noticed an irregularity that has been there since the original.
On the main page, there is a link on the username which provides a list of that user's blogs, but linked to the user.php file which limits the number to 5, but it also uses 5 db extra queries to generate that list.
If I change that link from Blogs/user/nick=username.html to Blogs/nick=username.html, then it provides a listing similar to the one on the main page, with 5 less db queries - it only uses 2 db queries, no matter how many entries you choose for your main pagination. The user.php link is still retained when the user clicks on "My Blog".
The advantage of modifying this comes when your site is being hammered by search engines, so I attach the modified page.php file which I shall include in the next release.
