List of Craig, Internet bulletin board number 1, since 1995, San Francisco, USA.
The bulk of ads are free.
Its ads cover over 450 cities around the world. Tens of millions of visitors a year. The site is one of the 100 most visited sites in the world.

New cities and regions are added by request to the editorial office from users. Russia is also represented in Craigslist, but so far only two cities: Moscow and St. Petersburg.
Most CIS countries, including Ukraine in Craigslist, do not.

Availability of the name in social networks.
Surely you have encountered when a certain site has accounts in Facebook, VK, Twitter, YouTube, Instagramm, Pinterest, etc.
But there is a different login everywhere, so it's hard to know whether the official account is or not.
Other sites have the same login for everything.

This service allows you to check for the use of a particular login.
Actually, I recommend doing this before buying a domain name. Then it will be very beautiful.
One more detail, say you can check the name and it will be everywhere freely. You run to register the domain, but it turns out that for example on Twitter this name is not occupied, but it is inadmissible. So first we register everywhere and if passed successfully, we register.

Enter the desired Nick and see where he is already occupied. So it's easier to pick up one Nick for all social networks in which you want to participate.
