Hello. I recently found out about this place and registered.
When using from Japan, I feel slow response, especially with FTP.
Still, I'm having fun.

As I was creating the web, I had a question.

When setting up a custom domain, what part of the domain recognizes the username?

The FAQ page explains:

You have a site called mysupermegawebsite.w10.site, then you can link the following domain names: mysupermegawebsite.com same as mysupermegawebsite.mydomain.com

If I set up a domain called "sub.example.site" ,Does the server check for "example" or "sub"?

I set one up to try and it showed me this forum.
Somehow, depending on the domain name used, I figured it wouldn't work well.
