So what's been up with Expanse, and why has the registration form been down so long? Well, Expanse is being discontinued as a product, and is no longer available for sale. However, if one is resourceful, they could pretty easily find a link to the zip. (Psst, view the source)
Also, if you purchased a copy of Expanse in the past, please feel free to use the software on as many domains as you like.
We'd like to apologize to everyone who has been emailing about the form being down. We haven't been able to comment on anything until recently, so please accept our deepest apologies. Currently we no longer are supporting Expanse, but if you purchased a copy, the forums will still be up for the foreseeable future.
Thanks for your understanding, your patience, and your support,
The Expanse Team.
