Feel free to correct mistakes in my comments and articles. Also, can you recommend a guide to English punctuation? (some are already suggested).
It is sometimes hard to find required software in Arch. Package descriptions in both AUR and official repos are too short and classification of packages is far from perfect. I currently try to accumulate editors efforts, related to creation of software lists, in Common Applications and related articles.
Also I am ArchWiki Maintainer – if you want to find some stuff in already deleted article or check correctness of edit (I am mostly interested in Java, Security and basic Arch topics, such as covered by Beginners Guide and Development), feel free to contact me.
