For anyone who is wondering about the difference between PRO and non-PRO on this site:
KudoZ - deciding whether a question is PRO or non-PRO
Sometimes people who are not translators use the KudoZ service to ask how to translate simple expressions, such as "I love you". While some ProZ.com members don't mind answering questions like these, others find them a source of annoyance. In order to meet the needs of both types of member, the category of "non-PRO" questions was created.
...
PRO questions are those that are suitable for professional translators.
Non-PRO questions are those that can be answered by any bilingual person without the aid of a dictionary.
...
If there is any doubt as to whether a question should be classified as PRO or non-PRO, it is generally suggested that the question be classified as PRO.
