Sorry to ask but first of all, how do you know about the portal under spawn? as there is no way down. except vip and stuff. (Since you registered not long ago)

sometimes i get really bad lag when i enter a portal which locks me in a place where i can destroy bricks on my screen which is still there on other peoples screens which usually re spawns if destroyed
 also the redstone under spawn is broke lava has gotten through and destroyed it
also the way the builder got the words to keep changing on the signs is amazing

as you can tell from the title i am new and i carnt wait to start playing everyday possible
