Nice post! 
Regarding the Email Management section, please include this explanation by the admin:
Remember to put alternatives like Zoho mail (for non-freenom users) and Yandex (for all users! 
)
Also, please include about using Filezilla when accessing FTP as it is a better way for downloading files as well as uploading multiple files quicker.
On the other hand, I really like this post. Pretty much summarizes nearly all questions users have. I don’t really like long posts that much, but this one actually got my attention (which doesn’t happen so often)
