Ishnu’alah Rosenoa!
Night elf roleplay is somewhat all over the place. A few groups roleplay in Feralas out of Feathermoon Stronghold. Others RP in Val’sharah, Azsuna, Winterspring and Ashenvale. The Silver Circle posts all of their events on their guild website calendar, for all to see. Anyone interested in night elf RP is welcome to join or spectate those events regardless of whether your character is a night elf or not. If you want to get your hunter out there a little more, you’re welcome to swing by and join us anytime 
There is also a night elf Discord, if you’re interested in a place to connect with other night elf players.
A few other night elf or kaldorei-centric groups I recommend looking into are:
- Keepers of the Moon
- Moonglaive Sentinels (f/k/a Sentinel)
- Starfall Sentinels
- Kalimdor Collective
- Falah’dure
- Moonshroud Covenant
- Jai’alator’s Vigil (f/k/a Wings of Kalimdor)
My best received character is hard to pick out. I think it would have to be Feyawen, but not because of anything particularly interesting about her. Rather, it’s because she’s a character that’s interested in learning about other characters and assisting other characters however she can. This results in people seeking her opinion for things, and occasionally means I put her own story and development on the back-burner. But she is enjoyable to roleplay nonetheless.
My worst received character is my highborne alternative, Mythera Darkthorn. She was only 5 when she and her father went into exile and she spent most of her life in poverty in the jungles of Feralas. But, because she is highborne, many characters approach her and mistake her abrasive personality for the cliche haughtiness and arrogance of an old highborne. It’s honestly a dynamic I love, particularly when people have the opportunity to peel back her layers and really get to know who she really is.
