Lead section edit trick
Normally, to edit the lead section of an article, you have to click the "edit this page" link at the top, and edit the whole page. This can lead to edit conflicts. However, despite the lack of an "edit" link for the lead, it is still possible to edit it as a section in order to avoid edit conflicts. Simply click on any of the section edit links, and then change section=x to section=0 in the URL in your browser window. Reload the URL and you will now be editing the lead section! This is probably most useful when an edit conflict is likely, such as on high traffic pages.
