I just bought the custom field plugin. I use it to allow visitors to choose their usergroup when register.
I made like it is written here and that works.
But now, I would like that members, once they are registered, are able to change their usergroup.
I put the custom field in the account tab as you can see on this screenshot http://prntscr.com/qlfhwc
but it doen's appear on account as you can see here : http://prntscr.com/qlfii7
The screenshots are made on admin account but it is the same with every usergroup.
How to do that please ?
