Frequently Asked Questions

To make it easy to find answers to your questions, we’ve divided the FAQs into categories. Just select the appropriate category from the menu to see all the solutions, or select All FAQs from the menu to see them all. The most popular questions are at the top of each category.

There aren’t any FAQs in the category you selected. You may have followed an invalid link, since we updated our FAQ database with new categories; select one of the options from the menu above, or use the site search tool to find what you’re looking for.

Thanks to everyone who helped compile the FAQs we use on this site. They come from a variety of sources, and we’ve tried to credit them where we can. If we’ve missed anything out, please let us know!
