1. I understand, which is why we need an option to choose which columns we want to display.

2. I currently use ARmember to manage user registration. In the registration form, I have added some custom fields the users need to fill up, those fields are saved in the WP_usermeta table.

If I get this addon (Custom fields) and move to use the wprofo registration form, all the existing fields will be lost. The users won't be able to see their data except for their name and email.

Do you have a solution?

All the data is stored in the wp_wpforo_profiles table as a JSON array. It doesn't add any columns in wp_usermeta table. This is in case of the saving information in the database.

In the members tab the area is not enough to add a lot of information. For example, you can create 10 new fields, and if we add all those information like a column there, we'll get a messed design. So we don't add the information in the member's tab. This information is visible on the member's account pages.

I wonder if every time I add a new custom field, will it also create a new column under Forum >>Members table?

Right now this table doesn't pick up WordPress usermeta!
