However articles/ videos that may contain other members of E-Girls but are not exclusively E-Girls videos are ok. I understand that this will be confusing. Therefore I propose that if in doubt just post it to both communities.It's not a problem if there are posts on here, I just want to avoid cross-posting too much.
So all in all
flower_ldh - Flower's activities as a group as well as member's solo activities.
exile_girls - Flower activities within E-Girls
Hopefully this will also benefit those who may just follow Flower and not E-Girls ^_^
