Hi, we are a 2 sided marketplace like Airbnb and we use Zoho Desk's Community Forum. However, we do not promote it to our customers because it does not autogenerate unique usernames. 

Zoho's software allows people to use their full name, which we don't want - otherwise other members can easily look up that member on Facebook and connect over there and this is a big problem to us.   We want to be able to control our brand and the conversations members are having around it.

Here is a screenshot of Zoho's Forum. We don't want to have to manually update each user's account so that it only shows their Firstname.   There should just be a read only field on peoples Zoho Profile saying 'Forum Username'
