The first step is to register with a Mx (Metadata Exchange) instance, shortly after registering your administrator will send you an email notifying you of your access details.
By default there are 3 levels of access, administrator, curator and guest. The basic differences between these rights are as follows: a guest will only be able to view models, a curator will be able to create and modify models and an administrator will be able to add new users; however different Mx instances may be set up with a variety of different access levels and rights, so it is best to consult your administrator to find out what rights and capabilities you have.
