What is the ruling on posting a topic in a forum titled "Let's all seek forgiveness here every day" in the Islamic section?

There is no harm in using a title like "Come, let us believe for an hour" as a reminder and an invitation to goodness and to cooperate in righteousness and piety. Indeed, some of the pious predecessors used to say that to each other, among them Mu'adh ibn Jabal and Abdullah ibn Rawahah.
