You can send a ticket. The ticket system has some problems. For example, you receive an email reaponse, but you cannot reply to that. You must return to the ticket page. And (when banned?), the login does not seem to work properly there, so I ended up needing to open a new ticket and reference the previous ticket. It worked, but it did take a while to figure a work around.
Let me inject that the CSR people have been uniformly nice and helpful. So this is in no way intended to disparage them in any way.
I was not able to contact live support on this page, but that may have been a staffing issue. I understand you may not have 24/7 staffing for a volunteer project.
So my suggestion is still to allow access to the site communications, at least for a while. Additionally, an improved ticket sysystem could further mitigate frustration in dealing with misunderstandings.
