The short answer is no.
If we hear of any vendor contacting our members privately (via any means) for things like trying to make a sale, trying to build their network or trying to ask for unsolicited feedback on their product, they will get a warning.
If it ever happens again, they will have their legs cut off and be banished from the Tribe forever 
We keep our Tribe as a safe space away from unsolicited messaging and vendor promotions and we will do whatever we need to protect the integrity of that very deeply.
If, however, you’re a Vendor and a Tech Tribe member has asked you in a thread to message / contact them so you can help them out with something, this is perfectly acceptable because it’s not unsolicited.
The simple rule is no unsolicited contact. Ever 
There are other member based organizations around the world (such as Network Group (UK), ASCII (USA) & SMBiT Professionals (Australia/NZ) that will allow you to send out communications to their MSP members and connect with them (for a fee). It might be worth getting in touch with them.
