Does MatMice ring a bell? It was a website made by 3 Australian sisters for kids to use, in the year 2000 running until late 2008. You could make your own webpage, and when I say webpage, it was just one, singular page. But it was AWESOME. It was basic, but that's all we needed back then.
My memory is fuzzy, since it's been so long, but I remember it being about 2006–2007, I was 12–13ish, and I made my own MatMice website to share with family, my sister’s boyfriend (lol, because he was family), his family members, and some classmates I trusted. The URL for any MatMice site was www.matmice.com/home/[your username here]. I have no idea what my URL was or if the Internet Archive even backed it up, but I remember having an About Me section, and I am pretty sure a photo of myself and my dog. I remember asking people I know to sign my guestbook and being really excited when I got a new comment. :)
The website was mega basic, and had built-in photos and backgrounds and stuff you could use. I'm pretty sure I had a blue repeating image for my background, and nothing really of substance on there. But still, it was mine.
There's not a lot online now that I can find about MatMice since it's dead and gone, with a lot of the old internet. Here's a few interesting things I've come across in my research of it:
Yesterweb Zine This is the webpage I stumbled across that made me work out what the website was I had been thinking of for all these years! It talks about the history and interesting information about MatMice.
