From their posts, you can understand, who are experts and who are not. Yet, if you want to expose your code, then it is your choice.
A word of advice.... you should be careful and check the track records of members, before sending TXT files or full codes. There are people, who under the guise of helping out, will ask for the full code, whereas they do not even have ability to solve simple queries. Best way to check is go to their profile and go through their recent posts.
