What is the ruling of Sharia on some forums requiring attendees to register their presence by mentioning one of the Beautiful Names of Allah, or a verse from the Holy Quran, or any other form of remembrance?

What was mentioned about registering attendance by writing a verse or one of Allah's Beautiful Names is among the good deeds that involve cooperation in righteousness and piety, and it is better than using phrases and slogans. This is similar to engraving rings with Allah's Names or verses from the Quran. The established Names of Allah can be verified by referring to specialized websites, such as Sheikh Ibn Uthaymeen's website.
