Would the poster tag this thread to their contact in how their inexperience is seen as humour. I think not!
We all start somewhere, hopefully we have mentors along the way that do not post the error and enjoy with others poking fun at the inexperienced who do not know the error. Where we all were at least once at times.
How would you feel, if it was you and you knew this thread was active and was inexperience to know your error. Or maybe had learning issues that made it difficult.
Laughing with others is good. Laughing at others is not!
