Just found the first snapshot of the TPT website. I have no idea why I'm posting this.

You can also discover other snapshots of TPT here.
It's really similar to the modern website. Even the "Topics that are not related to The Powder Toy should go here. Common sense and etiquette still applies." description of the "off topic" or now "General" descussions didn't change since 2010!
Yeah, I heard that the concept of TPT was pretty popular in 2010. I think there were even multiple versions of TPT run by different people, but I'm not sure.
There's an older snapshot here, when there was nothing more than a download link: https://web.archive.org/web/20100615010100/http://powder.hardwired.org.uk/
Im just happy i still have a save somewhere in the top 30 pages of browse.
