Hello,
HikaMarket do have an Access Level system which allow to activate or deactivate features and elements.
Via these settings, you can tweak what you want your vendor to see or do.
CF :
www.hikashop.com/support/documentation/1...l#tuto_configure_acl
1 - HikaMarket do not provide "private message" system. Customer can use a form to send an email to the vendor (without knowing its email), but the vendor will have the knowledge of the customer email to reply (just like the HikaShop contact form).
Afterwards, its possible to perform an integration with a Joomla component dedicated on private messages.
2 - Sure, with the ACL
3 - Can be also configure with ACL
4 - You can configure the fees in HikaMarket :
www.hikashop.com/support/documentation/1...ml#config_market_tax
Afterwards, if you want your vendor to only receive a part of the sale without the fee, it would require an "adaptive" payment plugin such as "MangoPay", "Stripe Connect" or "Paypal Adaptive" (note that Paypal do not allow to create new adaptive application)
5 - Sure, can be done with ACL
6 - It depends on your settings. HikaMarket allows to do the different cases (cf the tutorial)
The registration mode will define the baseline :
