I Speak Min, an online BBS which, as its name suggests, discusses about Min Chinese variants (Min Nan, Min Dong, Min Bei, Puxian Min, etc.), their writing systems, and more others I don't exactly know. It's entirely in Chinese, so knowledge of written Chinese is necessary. The last post dates around February 2018, but it might treasure some worthy stuff.
وَمِنْ آيَاتِهِ خَلْقُ السَّمَاوَاتِ وَالْأَرْضِ وَاخْتِلَافُ أَلْسِنَتِكُمْ وَأَلْوَانِكُمْ ۚ إِنَّ فِي ذَٰلِكَ لَآيَاتٍ لِلْعَالِمِينَ
"And of His signs is the creation of the heavens and the earth and the diversity of your languages and your colors. Indeed in that are signs for those of knowledge." (Ar-Rum: 22)
