judging by the date it says william joined,
im guessing january 2002 but you can get a mod to confirm this
oh yeah, heres a quote from Wikipedia explaining what a Moderator and an Administrator are
Moderator
The moderators (short singular form: "mod") are users (or employees) of the forum which are granted access to the posts and threads of all members for the purpose of moderating discussion (similar to arbitration) and also keeping the forum clean (neutralising spam and spambots etc). Because they have access to all posts and threads in their area of responsibility, it is common for a knowledgeable and trustworthy member to be promoted to moderator for such a task. Moderators also answer users' concerns about the forum, general questions, as well as responding to specific complaints. Moderators themselves may have ranks: some may be given mod privilege over only a particular topic or section, while others (called 'global' or 'super') may be allowed access anywhere. Common privileges of moderators include: deleting, merging, moving, and splitting of posts and threads; closing, renaming, stickying of threads; banning,
unbanning, warning the members; or adding, editing, removing the polls of threads.
Administrator
The administrators (short form: "admin") manage the technical details required for running the site. As such, they may promote (and demote) members to moderators, manage the rules, create sections and sub-sections, as well as perform any database operations (database backup etc). Administrators often also act as moderators. Administrators may also make forum-wide announcements, or change the appearance (known as the skin) of a forum.
The term prune used extensively in administration panels is synonymous with delete or remove. The term comes from pruning, the practice of removing diseased, non-productive, or otherwise unwanted portions from a plant.
