I apped because everyone said the game was super backtag friendly. I might just be unlucky, but I didn't find that to be the case at first. I think your mileage will vary and I am sure there are backtag friendly people, you might just have some trial and error before you find them. There's about 2-3 posts per day, some will get a ton of comments, some will get barely any, mostly depending on how much effort you put in, but sometimes it's just bad timing. Looking back a few pages I don't see many that get under 70 or so.

No clue what kind of character you want to app so I can't tell you if their type does well, but there are some that do better than others. If your character isn't self-motivated, you'll have to do some extra work to get them involved. A lot of the plots are designed for characters who are proactive. Right now most of the story is being driven by official game-changing missions that characters have to volunteer for, rather than specific plots being piloted by a mod. The best approach for me so far has been deciding what I want and approaching people to do it with me. Certain characters might not be interested in that right away though.

Overall just be patient and persistent. I've been here for a few months and I'm just starting to feel comfortable in this game. You be lucky and find your place quickly, but it might take a while too.
