@baris yes, this was our method; however, there have been many real new users who wanted to use those fields, and it was taking a lot of time for us to fill in their info manually, so we had to abandon this method.
I am interested in contributing to the NodeBB, I am studying the source code. For now, I can not contribute.
I wonder if anyone is interested in a plugin for a vote on a topic.
Someone would also like this feature and who could help in the development?
