If my user page feels too short, you can ask on my talk page.
I'm also expanding articles if they're stubs (articles that are too short) and I also add the citation to that info. (or summarize material in my own words)
I spell the suffix -ize with a z (e.g. ionize) and I create edits on mobile.
The article Infrared is now B-Class, Probably because I added a bunch of reliable sources and expanded it a lot. (And made it better using a lot of tools)
