Thanks for stopping by support. There are three legs to this particular support chair :)
2) This FreshDesk Portal which is primarily for handing tickets and issues at this time (where you are now :)
FreshDesk is used so users can get support via email without needing to create accounts.
To create a ticket click "New".
3) Known issues including: feature requests and bugs are tracked in JIRA (all JIRA projects are also listed here).
When ticket is identified as a bug or feature request which goes beyond the scope of quick support a JIRA issue is created and they are linked together. When the bug is fixed or resolved the ticket holders/creators are notified.
