Enfold support account

I purchased two copies of Enfold having registered twice with Envato and Kriesi. Can I change the Kriesi support profile so it doesn’t have my company name (i.e., username) any longer? Or can I just create two new Kriesi forum accounts using its corresponding purchase codes? Envato’s account info says I can change it at least once each.

Therefore, for my own future purchases, can I get my own “company name’ back?

While I’m at it, does one need to create a forum account for each purchase if the company/client is the same?

Please advise.

Thank you!
