This is probably already been mentioned, but we should really have some type of GPS, that lists people on the server, where they are at that kind of stuff, maybe a teleport to them button, but you have to get their permission first. Because not everyone is on the forums, so not everyone can use the Locator Topic.
And @Mr_H2 and @Sierepica_Fuzzywalker and @Emman_Jumpsong1 had good ideas about the more advanced players be able to look at newer players stats and missions to help them better.
And adding on to that idea, you could have a bio or something explaining what the player is looking/wanting because sometimes, I like to collect stuff and find things that don't require a mission, so it's hard to explain to other players.
And maybe they can add in a directory of sorts, for chatting, because lots of times, I'm telling a player and might have to use the characters name, but the chat doesn't like that I'm using a name, and it gets tedious explaining.
Sorry for a long post.
