<news> "Top-10 Users" list added

[Nickolas]

Now that Progopedia has over 20 registered editors, we feel that their
contribution deserves public recognition. "Top-10 Users" list shows
the most active editors along with links to their personal pages.

Remember that you can personalize your page by creating a new entry in
"User profiles" section of editor's interface. Like on the rest of the
site, the markup language is Markdown ( http://daringfireball.net/projects/markdown/syntax
). Feel free to add information about yourself, including your contact
details, links to your websites or projects, etc.
