I live in Edinburgh, United Kingdom. Can I use this site, or is it only for the USA ?

Sure you can, we are Global..

Ask away! However, if it is something local, like the best pub in Edinburgh, you would be better off to check locally.

Sure you can but when asking a question it may be helpful to include your location, especially if you ask an electrical question

Hi Chrissie... You'll find people on the site from a number of different locations.

There are people on here from all around the world, Europe, Asia and more.

Hello / Kia Ora

Anyone can use this site if they wish to , heck I'am from New Zealand.
