1) I have already an account for working inside Webmin. Personally I clone root then I delete root and anonymous. Is it a correct behavior for Virtualmin the following: I don't want to set up an "Automatic Administration username" when Creating Virtual Server. I would like to pick a custom one, one already created, the one I use for Webmin. This will allow me not having too many users (it is only one virtual server). By default, if the user exists in Webmin, Virtualmin will not allow to use it as Administration username.
2) You have to find a way to keep the options set when there are failures choices inside the "Create Virtual Server" form. For example, I forgot to set up an Administration password before clicking on [Create Server] button. I get the error for missing password, but getting back to the form it is the initial form, all my options are gone.
