I have these old site screenshots:

Here’s a Ugandan Knuckles screenshot that I stole from Ralph:

You can probably find some of the fighting game stuff by just going to the Arcade Fighters groups.

I was able to find some of the “Darkboy is dead” stuff just by searching “Darkboy sticknodes dead”, but here’s the only video about it left on his channel as far as I can tell:

Here’s the tattoo post: https://sticknodes.com/activity/p/1411708/
Here’s a meme I made about it: https://sticknodes.com/activity/p/1412284/
Here’s a screenshot:

@ralph I know you probably have some of these.

Other things that could be on the iceberg, if you want:
I just remembered the Rick Astley 3AM splash screen Easter egg, so that could be on there if it’s not already. (I don’t think I have a screenshot unfortunately)

You could also include Ralph saying the default is named Felix (https://sticknodes.com/activity/p/1318725/). He’s also said it’s Peter (https://sticknodes.com/activity/p/1381981/#acomment-1382046).

You could probably include a bunch of the site groups, such as “Guests say the darndest things” and The Silly Council.

You could probably include last year’s “Rock, paper, Krampus” event. (I don’t think I have a screenshot)

You could include that time Wacka broke the site. These are my only screenshots:

You could include Nikocado Avocado looking like the default.

Maybe you could include that time people changed their profile pictures to a single color. I think there was a group for this, but I don’t remember its name. Here’s a screenshot:

You could include Ralph’s mysterious request (https://sticknodes.com/activity/p/1372169/).

You could maybe include franchises that are relevant to the community, anything from Dragon Ball to Skibidi Toilet.
