Just a reminder and it's something I need to tailor a bit better to as well, but as a rep you represent a company, and I know I'm guilty of it myself but sometimes we have to be cognizant of the things we say....
We need to be a positive influence to the community, be willing to help, be friendly that sort of thing just an all around good person.
So to the guys above if you think you have what it takes, research the products, have a belief in them and make sure other members will applaud the company's decision to bring you aboard. Dont be afraid unless YOU truly yourself believe you are not ready.
