Main Vendor Groups - whats it for?

-- HikaShop version -- : 2.6.4
-- HikaMarket version -- : 1.7.2
-- Joomla version -- : 3.6.2
-- PHP version -- : 7.0
-- Browser(s) name and version -- : All

Hi
I'm setting default ACL for my vendors, but I cannot find any documentation on, what the last group is for?
Should the "Main Vendor Groups" have checkmark in 'Author'?

When my vendors sign up, I default them to 'Author' group in Joomla.

What does it do?

Hi
I still don't understand the connection here.

I have a top Administrator of this Joomla/HikaShop/Hikamarket website:
Joomla username: flexsus (Super User ACL)

Besides controlling everything in Joomla back-end as a Super User admin, I have a top Vendor, me - a Vendor which controls all the vendors, right? = "Your Vendor" (3rd tab in config)
How is this "Your Vendor" associated with a Joomla User? By it's e-mail address?
Is the purpose with this Your Vendor to give some special access in front-end of Joomla?
If, Your Vendor is associated with a Joomla User, should this user then be put into e.g. group 'Administrator'?
And then this 3rd block "Main Vendor Groups" should have checkmark in 'Administrator'? - right now I have nothing checked here.


About the registration, I understand this part. My vendors are put into group "Author" when the sign up as vendors.


Something that I'm trying to achieve is, that I as that Super User administrator and as the main Your Vendor has access to the Order History in show i front-end. But all my vendors should not see and have access to this part.

Best regards,
Henrik
