Stadium tours

I have been reading about various people/groups being invited on stadium tours and was wondering what criteria was used for selection. I am a long standing (and suffering) STH and would like to know if I may expect an invite in the near future, especially as my Millwall supporter friend was telling me all about his Falmer tour recently.!
I assume these visits are over and above the hard hat seat selection tours which all season ticket holders will be invited to later in the year.
(waits to be bombarded with links to 300 earlier threads)

At the moment we are not doing stadium tours for the general public, I suspect your colleague came to one of the marketing presentations for the 1901 Club (premium seats, with hospitality) - to which all STHs were invited to by letter. More details here...
