I've never used the website because I disagree with the Terms of Service:
Content Submitted or Made Available For Inclusion on The Service
Aresta Enterprise does not claim ownership of Content you submit or make available for inclusion on the Service. However, with respect to Content you submit or make available for via the Service, you grant Aresta Enterprise a perpetual, irrevocable, world-wide, royalty free and non-exclusive license to use, distribute, reproduce, modify and publicly display such Content on the Service.
You will be responsible for, and indemnify and hold harmless Aresta Enterprise, against any claim arising from any content that you submit or make available for inclusion on the Service.
So, basically, you still technically own the copyright, but you allow them the irrevocable right to use your work forever. It sounds scary to me. Unless someone buys the rights, I'm not giving them the right to use my work forever.
