Ok...Maybe Uncle Nastro is skeptical but its sometimes safe.
Personally, I am very cautious when companies (especially alleged IT companies) us public email servers such as yahoo, hotmail, gmail and excite to conduct business. Yes its tacky, but it goes beyond that. It says something about the it being a company at all or a very tacky and disorganised one if it is a company.
Sadly, this is not always the case. There are many large companies (Eg. Holiday Inn etc..) uses these mailing addresses to put add in the paper. They do this as apart of their 'head hunting' strategy. It usually depends though on the post.
Free Thinkers are those who are willing to use their minds without fearing to understand things that clash with their own customs, beliefs for privileges. This state of mind is not common, but it is essential for right thinking; where it is absent, discussion is apt to become worse than useless.
