Why hello there and welcome to here.
I just wanted to throw this out as a concept to see if anyone else would be into the feature. Quite a few free boards out there have an option for the implementation of a calendar to schedule events and even link back to topics related to those events. The advantage is that it provides an at a glance look at what is coming up with times usually synced to whatever an individual user has their timezone set to within the forum. So for something like a meetup within GTA V it eliminates a lot of the need to qualify what time of day an event is happening by providing a timezone for you. It's also good for general organization as it allows people to plan around other events.
Something like a community calendar for the crew section here could help with the organization of death matching tournaments, racing, circle jerks, whatever. Click on a day, you're shown a list of events. Click on the event, you are taken to a forum topic with more information. Like so.
I've noticed quite a few crews (obviously mine included) mainly create their own forums for tools like these. Or at least that was my main reason for going outside of GTAForums since the focus of the crew is meetups. If we were to have these kinds of feature sets here it might keep more crew activity within these boards. A further advantage to this for crews is obviously that more people are likely to see any events you have coming up since GTAF's user base is quite a bit larger than JoeBlowsFreeBoards.com It could be a great addition to our Crew Events section.
It'd also be a good idea to be able to separate events by platform. [PC][XB1][PS4] ... that way you don't have overlap for an event that isn't actually taking place on a given platform.
