When you are e-mailing, chatting online or exchanging Instant Messages, you must rely on mere words to make a good first impression.
You will want to carefully choose your words so you don't come off as offensive.
Most of us understand the importance of being clean and presenting ourselves in a positive manner in person to person meetings.
No flaming, personal attacks or abuse against others. Notice the word "gentleman." When a t-girl feels that she is being treated with the dignity and respect befitting a lady she is in heaven.
Here is a good rule to follow; Don't refer to anyone as a shemale, transsexual, transvestite, etc.
