I’ve noticed that some Discourse instances refer to their community as a forum, and some refer to their community as forums. For example:
Welcome to the forum
Welcome to the forums
Is this just an anomaly of the English language? — are they both correct? Or is it one of those “everybody does it and there is no reasonable hope of correcting this” kind of things?
I personally would use the singular form when referring to a specific community, Like:
the Discourse meta forum
