I am holding off on my review in favor of throwing out some suggestions first.
1- I would add a way to move the added fields order of appearance amongst each other and amongst those included in bbp. As it stand right now the questions are randomly put in the middle of bbp information, ideally they would be placed under the profile for me.
2- An ability to add and remove fields beyond four of them.
3- The ability to limit the length of responses.
4- The option of responses being answered by a drop down menu, radio buttons or boxes.
3- Fixing the bug of fields have two "::", such as "Favorite Games: :".
Overall though I do like what you have done. It is very clean in its presentation and it does work even if it is not perfect. Thanks a lot for the plugin. :)
