I found UF to be a complex input device... UF does support manual comptex differential/drivitive's input script's.however I also found that there was several Information Technology pools that could be established as drive beds for the knowledge values;= Some people may not be up to par on the ITbase contained there in? So. you could down load these script's and visually browse the rendered product..Umm..So in conclusion; I some times find myself becoming stuck on the topic of UF or any other widely used applications? A skill level rating would be a though for more pie... Don't you hate it when your topic doesn't fit-in??
