Forget Six of One - Enjoy the alternatives.
Six of One is no longer relevant to Prisoner appreciation. Most of the talented members have quit in disgust at the antics of the current coordination team, leaving behind only a small number of talentless sycophants. In the modern days of the internet and newsgroups, it is no longer necessary to join a club to learn information about the series, or to meet and converse with like-minded individuals. Indeed, Six of One admit this in a 2005 Society magazine:

In the last year (as of October 2005), the Society has only held one event - a poorly attended Convention (described by many as "embarrasing", "lacking atmosphere", "badly organised").
Outside of the Society, however, countless events have taken place including Location Tours, conventions (including PM2005 and PM2006, both of which raised over £1000 for charity), book launches, and Local Group activities.

Prisoner guests at PM2005 - run independently of Six of One.
Details of these events, and future ones, can be found by visiting The Unmutual website.
In the last year, Six of One has not created any new merchandise of its own, apart from the self-referential mailings they provide (which contain little or no interesting or new information regarding the series). They have, however, released a bootleg DVD (click HERE for more details on this). They have also been SELLING (for profit - totally against their non-profit making remit) items which were given FREE to them by the Sci-fi channel to promote their screening of the series! Outside of the Society, however, the following merchandise has become available, independently of Six of One, in the last year or so:
Book reprint: The Official Prisoner Companion, by Rob Fairclough.
Prisoner Novel: The Prisoner's Dilemma by Blum/Booth.
Book: The Prisoner: The Original Scripts, Vols 1&2
Magazine: The Prisoner: Official Fact Files
Magazine: The Danger Man Collection
Plus a host of fanzines, websites and the continuing availability of a Patrick McGoohan interview CD by Roger Goodman.
More Prisoner books, Location tour events, Conventions, and Local group meetings have already been confirmed for 2007. Visit The Unmutual Website, which is fast developing into the largest known resource of Prisoner news and information, regularly for more details. Daily debates regarding the series continue at the alt.tv.prisoner newsgroup. Other than making a mockery of McGoohan's ideals and wasting over £20, there is nothing to gain by joining Six of One. Instead, stay out and enjoy the alternatives.
In addition to ignoring these items themselves, the Society appears to be deliberately ensuring that genuine Prisoner fans don't become aware of these items by *any* means. Below is a piece from an article in one of their 2005 magazines, where they claim no independent events or items exist:

Also, in April 2004, coordinator Rob Beale confirmed this tactic of denying the existance of non-Six of One projects, in an email to an ex-member of the Society:
"While I was there [Portmeirion] I had a look at the pc in the Prisoner shop and as expected, the unmutual sites [sic] were in the favourites folder. Naturally I deleted them and added all the 6o1 sites."Rob Beale, 17/4/04
