Take a look at
Clan Discussion and see if there's any clans that suit your personality and level of activity. Check for public Discords if you're looking for a social clan, for clan tags if you're wanting in-game activity, and/or for forum posts if you're looking for a place to post with.
You mentioned in-game activity and forum events? Judging from the
Clan List both (xp) and [Damned] are both pretty active in war. If that's your niche, try a clan like them out.
Anyway, I don't really feel like there's many contributions that can be made to this thread outside of clan recommendations and the simple advice that you've already received, so I'm going to close this thread. If you have any questions or concerns, or want to potentially reopen this thread because you feel there's more discussion to be had, please send me a PM.
