I have purchased JomSocial for use on two different domains:
mfa-sibs.org
northrivercommission.org
I have tried to submit a support ticket for northrivercommission.org and the site tells me that only mfa-sibs.org is supported. It says I should go to my account page and change the supported site. When I go to my account page, it will not let me change my supported site, or ad a supported site - even though both sites are listed.
Our license system allows you to use the extension in all your personal sites but we offer support to one domain only. If you need to get support for more than one domain you need a new license.
Let me know which domain you want to set as supported domain.
