I was an old player. My username was ZaKdeBoss. I didn't have a rank or anything. But I have some screenies of 2015 Skyblock if anyone would like them.
If you realized that you are a veteran player then you must be thinking "wow did I really just spent that much time on a Minecraft server when I could of used that time on doing something else instead???!!!"
I first logged onto skyblock.net in August 2012. I've had that exact epiphany you've described at least 3 times now.
Lol I remember you. Weren't you friends with tsylor1221 or something? If not don't hate me, memory is fuzzy
