Talk pages are for communicating with other users, especially about articles and creating this wiki. There is a talk page attached to every other page, just click the "discussion" link at the top of any page to go to it. As with regular links, talk pages that are red links do not exist, and talk pages that are blue links have already been created.
Logged in contributors also have a personal talk page. This is found in the same way, by clicking the "discussion" link at the top of a user page. If you have a new message on your talk page, you will see a bright banner accross the top of all other pages. Click the link there to go to your talk page.
There are talk pages for non-logged in contributors, but these may not always be useful. Because they are linked to IPs, and IPs can change between visits, the messages may not get to the right person. They are used to explain blocks of IPs, but may not be very useful for real communication. This is another good reason to create an account.
It's possible to add a new section to a talk page without opening the whole edit page. Just click the "+" link next to the edit link. You will be given a space to enter a title for your new section, and to enter your comment. You can then save, and the comment will be added as a new section at the bottom of the page.
If your talk page gets too long, you can create an archive by creating an "Archive" subpage to your talk page (e.g. User talk:Example/Archive). You can click the new link, and copy over the older comments.
Some other hints for talk pages:
- Sign your comments by typing "~~~~". This will add your name and the date.
- Add comments to the end of the page.
- Keep your comments polite and friendly. It's always best to be civil, even if things get heated.
