We are planning to start a new topic in the Exchanges section (since we are a cryptocurrency exchange by a definition) by the end of this month using that brand new account.
Good decision to start fresh, and best to lock this topic when you make the final transition.
My suggestion is to create new account without any extension, just make
eXch or
eXch_exchange if any of this user names are available.
PS
Can you tell me more about eXch mobile app?
I saw that it's open source, but I am not sue how safe it is, since it's community made project.
