Description

Welcome, This is UndefinedRP. Emergency Library County. We arent just any RP Community but we are a special organized community. Providing a different immersive environment and experience. You may think we only RP. But our main mission is to demonstrate that our mafia rules the whole ERLC. Known as SRT. We have a special way of showing others who we are and a special way of running the whole clan itself. So why not join us?

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
