There should be a way to have several accounts in BSS, so you can change your Profile. Since for each profile they leave us 5 spaces to publish web pages, they should allow us to buy several keys and that each key has an account and the system allows us to put multiple accounts to pass between them without problems and you can manage several web pages, without deleting the bss data and entering with another KEY or another PC.
It would be cheaper for you to buy hosting and not have multiple accounts
I agree with @richards on this. Hosting is not expensive and with it you get a lot more freedom with your files than you do with the BSS hosting. Personally I wouldn’t be using BSS hosting for my main site hosting, I would use it more for testing purposes, but that’s me. Check around you’ll find a lot of cheap hosting.
