What may talk pages be used for?
Talkpages are not for general chatter, please keep discussions on talk pages on the topic of how to improve the associated articles.
User talk pages
Can I do whatever I want to my own user talk page?
Most editors treat their user talk pages like regular talk pages, and archive the discussion periodically to a personal subpage if the page gets large.
Your personal talk-page is primarily used for direct communication between editors, you may decorate your userpage or talk-page as you see fit but be aware that talk-pages are for communication between editors, and off-topic discussions should be kept to a minimum.
If you are having a disagreement or a problem with someone's behavior, please read w:Wikipedia:Resolving disputes.
