When I try to submit an Incident here in the community under the Support Incidents tab, it just disappears. I have also tried emailing support<at>axosoft.com.

Any ideas? 

Tim,
 
Thank you for bringing this to our attention -- we have identified that this is in fact a defect -- This defect only affects the new SSO functionality within Customer Portal.
 
A temporary Work-around for this, is to edit SSO Contacts and check the "Allow View Own" options for Defects, Features and Incidents.

Thank you,
