Hello steviec1,
welcome in SEBLOD world.
For beginning with the User management by SEBLOD, I advise to have a look at documentations and videos listed below.
SEBLOD allow you to add any kind of field you need, in each content type. So no probleme with a wysiwig.
By cons, with a wysiwyg, be sure that the user have good right to see it in front end.
Regards.
Lionel
