The ticket only event has been in the planning for the last couple of weeks and will see members of the Trust and the Supporters Club amongst others getting the chance to talk directly to the new City boss.
Mackay will take two players with him this evening, skipper Mark Hudson and the one and only Robert Earnshaw will both, along with the boss, speak to supporters in intimate surroundings.
More of these events are planned so look out for news stories promoting them and offering details on how to get tickets.
Tonight's event has been publicised on this website and via CCMB and by the Trust and Suporters Club themselves so there was no secret.
A full report of the evening will be published here when available.
