SearchSuite is a userscript that provides user control over search results: it can strip them down to a single-spaced list, sort, and more. Most of its features are presented as menu item toggles to turn each feature on/off. Each menu-item-controlled feature works on the output of all the others, in both their on and off states. Feedback and feature suggestions welcome.

Wikipedia:Typo Team/moss just got a fresh batch (from the July 20, 2018, database dump) of articles with misspelled words, and words missing from Wiktionary. Stop by and experience the satisfaction of fixing all the misspellings in an article on the topic of your choice!
Sometimes Wikipedians sound like they are speaking in a foreign language, even when they are not. This is because Wikipedians have created a great number of specialized terms (jargon) pertaining to Wikipedia and the activity of Wikipedians. Fortunately, being the encyclopedists that they are, they have also created a Wikipedia Glossary to explain these terms.
Remember, actual encyclopedia articles should be written in jargon-free language which is readily understandable without specific knowledge of the Wikipedia project.
