Help:Archiving
Archiving a talk page is a quick and easy process.
Step 1
Enter the edit view of the talk page and copy all of the content you wish to archive.
Step 2
Choose a page to be an archive. Normally, it would be "(namespace) talk:(pagename)/archive"
Once you do this, paste the content on the page and add {{Archive}} to the very top of the page.
Step 3
Remove the content from the talk page, leaving an edit summary saying something like "archiving talk page"
That's all!
