I know I had one. I remember making it on my old computer.  But it doesn't seem to have come. Do I need to make a new one?

Some older accounts were converted here back in 2016 when work began and yours would have been included in that. If you changed or added the avatar after that, it wouldn't be reflected here. You should be able to save your avatar below by signing in with your wikispace details then heading to the account page and upload it here. However this site supports larger and higher quality avatars so you may want to make a new one.

Ok, I made one. I'm not sure if it's actually "higher quality" or not, but it's bigger.
