A few minutes ago I have removed old inactive user accounts. All users who never logged in for time longer than 2 weeks are out.
Because there is a still more and more useless comments spamming with links to some URLs, I did these changes:
1. Unregistered users couldn't provide the link to their homepage
2. All registered users having their homepage link in their profiles will have this link in their comments now, but only as 'www' text.
So this is a bonus for all people who will register on this website.
The last change I did today is showing the users avatars in their comments.
