Just suggestion, I like the personal license $2/month ... it's super cheap but the big reason I'm staying away from this plan is because it offers only 1 user and IMO, it is better to have a minimum 3 user access level accounts in DA for best security. For example, we can have an admin account by default and we should not use this admin account to create domain.
Then from this admin account we can create a reseller account and he should not have any domains and finally this reseller will have to create a normal user account.
So, our website should always use normal user account not reseller or admin.
If we use admin account to create a website, and if somebody gained access into our admin account through web vulnerabilities, they will be able to get DA admin access level (might be with the API access etc). So, having 3 access level increases the file permission security in DA box. Maybe we can have another plan that can have a minimum 3 users (less than $15). The 10 users / $15 is overkilled because I don't need more than this to manage own websites but this plan is great if i want to host few external users in DA.
In brief, I feel like using $2 plan, we are losing one of the security features (access level) in DA.
