They do have a database of sorts on the ticketing system. I know that much as they take everyone's details for tickets. The only communication I get that I can think of is my yearly season ticket renewal letter.
I do receive regular emails from the ICT Community guys though telling me about upcoming courses and activities for the kids as my daughter has been on the Hotshots courses. They are far better in this regard than the actual club.
We truly are woeful and amateurish when it comes to promoting the club to people and businesses in the community. Hell, even with our own fans at times. You could walk and drive round Inverness all day and unless you went past the stadium I doubt a visitor would even know we had a football team let alone where it is etc.
My understanding from the fans meetings the start of the season was that Danny M was to be championing this aspect of things but obviously he's been moved to a different role (not that anyone's actually told us this officially of course).
