This CAPTCHA is horrible! It will probably lower the number of actual people that register on the site due to frustration. Please change it!

Hi, I would like to create a lemmy server for my country. I am wondering:

1. Would I be able to customize it? For example, remove the NSFW option entirely, or removing the need for a captcha?
2. Does it have to be connected with lemmy.ml ? For example, I wouldn’t want all communities (such as Linux@lemmy.ml, Metal@lemmy.ml…)?

Thanks
