I really like this idea! Did you add it to Runelabs? I'd vote for it.
yeah it's called "Old NPC's Revival" (1590 at the end of link)
it had some supporters, but the amount of supporters always goes back to 0 as soon as the "round" ends. For example, it will go back to 0 on 26th May (in 3 days from this post on), no matter how many supporters it would gather.
