1.) There are d@ting sites to meet all possible d@ting needs. If you are looking to date a clam worshipper, don't register for JustSquirrelWorshippers.com in a effort to cast a wider net.
2.) Read profiles and respond accordingly. Don't respond if you are outside of what the person specifies they are looking for.
3.) Don't deceive people about your job, income, # of children, marital status, weight, age ETA: or whether you smoke and/or drink alcohol. Believeing no one will respond to your profile unless you lie about X is no reason to do so. They'll be more angry to find out they were lied to.
4.) Do not use a picture that has been doctored so it looks little like your true self, a picture taken more than 3 years ago, or a picture taken before a significant change in your physical appearance, such as gaining/losing 20 lbs, significant change in hairstyle like drastic coloring, cutting, or losing hair, or going from a military-style crew cut to a mohawk. Don't use pictures that may respresent yourself differently, i.e. a pic in a martial arts uniform if you wore it once for Halloween, or sitting in a canoe if you hate the outdoors, posing with your cousin's pit bull if you dislike dogs.
5.) Sending/getting a message or wink doesn't require a response if the recipient isn't interested.
6.) Do your best to proof-read & spell check your profile.
7.) A first message should be like a first greeting IRL. Do not ask for a phone number or date right away.
8.) If someone's profile reads: 'Party X Sucks Twinkies", and you are a card carrying memeber of Party X -- move on. Don't message the person to change their mind, criticize their opinion, or to troll.
9.) Your 1st message should NOT include any of the following: lewd or derogatory comments, guesses at Scrabble skill-level, instant false kinship ('You like Bones?! You must be my SOUL MATE."), generalizations about an entire gender, or "You look like my ex/3rd grade teacher/future parent of my child".
