Welcome to the wiki!
I'm purplebook163. I've been on the wiki for about 4 months now, so I'm a bit new myself. I thought I'd take a minute to show you some cool stuff that isn't in the tutorials and welcome guides.
If you want to leave a smiley face, you can! On the wiki we have all of the emojis Scratch does, including Error. Smiley not recognized., , , and ! For a list of all of the emojis and how to make them, see this.
I see your userpage is a little bit blank... One thing you can do to customize it is add a header and/or index of subpages. Here's my header, which is based off of jvvg's header, and here's my index of subpages:
User:Purplebook163 • User talk:Purplebook163
User:Pb163/Header • User:Pb163/Talk Page Header
To view my list of subpages, you can click "show" on the top right hand corner.
You can also make a background, change the color of the text, add pictures, or really anything else you can think of as long as it follows the Community Guidelines.
If you'd like help making a header, index template, or anything else, let me know and I'll do my best to help!
Also, I thought I'd leave you this, just so you have some helpful links.
