I'm in the exact same boat, to the letter. I'm an individual shareholder, for whom the club has contact information (they have marketed to me many, many times, and I'm an online overseas stream subscriber) and to whom the club by its own rules has an obligation to provide notice of an AGM. They chose not to provide that notice.
MCT, to their credit, did provide notice. However, I also didn't receive the Zoom link despite signing up online.
From neither party is this good enough. The Club is relying on the current good feeling around the Dougie revolution; if they blank shareholders and supporters when times on the pitch are good, they can see what happens when times on the pitch are bad. MCT talked a good game about democracy and oversight, but when push came to shove they didn't provide a means for remote fans to attend the AGM, despite their promises.
Socks are needing pulled up both in the boardroom and at MCT. Complacency is setting in. Sort it.
