Hello, I'm Praseodymium-141. You can call me Pr-141 if you'd like. I have made over 14,243 edits to the English Wikipedia (usually chemistry-related, although I do sometimes participate in other areas, such as AfC and NPP. I also sometimes contribute on zh wiki, and occasionally on wuu wiki. If there is any problem related to something I’ve done, please tell me on my talk page.
