How is information collected?

Your information is collected in two ways.
  • Firstly, by browsing this forum the phpBB software will create a number of cookies, which are small text files that are downloaded on to your computer’s web browser temporary files. The first two cookies just contain a user identifier and an anonymous session identifier, automatically assigned to you by the phpBB software. A third cookie will be created once you have browsed topics within this forum and is used to store which topics have been read, thereby improving your user experience. We may also create cookies external to the phpBB software whilst browsing this forum, though these are outside the scope of this document which is intended to only cover the pages created by the phpBB software.

How do you store my password?
