/*
	Remind if...
	... one or more language entries are missing
	
	Taking into consideration
	... admin is NOT able to change the field type later

	Admin is able to preview/test the input and output of a profile field at every time.

	If the admin adds a field, he have to enter at least the default board language params. Without doing so, he
	is not able to activate the field.
	
	If the default board language is changed, a check has to be made if the profile field language entries are
	still valid.

	* Show at profile view (yes/no)
	* Viewtopic Integration (Load Switch, Able to show fields with additional template vars populated if enabled)
	* Custom Validation (Regex)?

	* Try to build the edit screen with the existing create screen...
