Post installation

I see that there is a statistics module that shows the recent visitors, hostnames, referrals and the pages they have visited on the drupal site.

However, is there a way to get a graphical represenation of the visitor count? Either pageloads or unique visitor counts.

After upgrading from Drupal 4.3.1 to 4.4.0, block paths have stopped working for me. What might be the cause of the problem?

I do not want to allow new users to create usernames with spaces in them. Is there a way to hack into the modules that do this and change this permission?

Thanks

How to sort node in alphabetic order instead of chronological one?

Is it possible some way to show image thumbs form image module?

Say as in story or blog when I write [image:20] I see it's thumb (filters enabled). I tried but it doesn't work. Maybe I have to make some php block?

Thanks

click on update, and it will behave as if it's
updated with respect to times, but still say 0 items

I have followed the INSTALL instructions, but its not works

any idea?
