You will need some advice about string selection, unless you are one of the few people who already know the string they intend to use,
We have prepared a guide that should help you to select the best type of string to use. Once you have done this, you will probably need to do a little research of your own.
The guide was prepared some time ago, but the basic information is still correct. The theory does not change, only the specific strings, and many of these have been popular over several years.
The guide should be updated later this year, after some essential website changes have been made. These should make it easier for you to view all the website information pages on your mobile device.
