Everybody knows about online matchmakers and much people have had a date themselves. Because of using profiles you know what a single man or single woman wants.
Of course you will need to add good photos, at least a few!
Don’t look cantankerous on the pictures, but smile.
You need to sell yourself on some kind of way, showing yourself is absolutely the best way on a new or popular website!
Also try to describe youself on a positive way and tell what you do in real life and what you seek.
People who tell much about themselves also have more chance to meet someone with the same hobbies and way of life.
