I saw that the calendar (the one in the forum) is disabled, is it broken ?
It would be great to have a calendar with the release date of games (with a link to the list of games), events (such as E3 and KS Nations Event), news, sales, and perhaps the anniversary of members (or not). For games or events that have no specific date, they may appear inside a space below the calendar (June would appear in the month of June, spring would appear within 3 months of spring, and so on).
This one looks great : http://www.easyphpcalendar.com/demo.php (the MyBB one is quite limited)
If it is a matter of time to manage it, I can offer my time
