With the calender events they are on an approval only basis bacause only events hosted by AW should be placed on there. Since events hosted by us can be run by anyone that sends in a mission this means that if we allowed anyone to create an event we would end up with a lot of clutter on the calander that is definitely not needed. As it stands all members of the admin team can approve posts on the forums and calender.
We like this approach as it keeps these locations clean from spam and only approved events end up in these locations.
Personally my advice would be to notify a member of staff when these events have been posted so that they can be approved within a timely manner.
We have looked into Patreon in the past however they take a cut of all donations made, this makes it hard for us to justify the cost and we dont feel it is a good fit for the community as when you donate to us the money should go to us for use on our servers. This is why we have not implemented this feature at this time.
