I worked on the article about ‘Skype’: https://en.wikipedia.org/wiki/Skype
This article was improved in a various sections. I plan to update the outdated information in sections such as: the ‘Usage and traffic’ section requires updates to reflect new information based on whatever information is available on the internet; ‘Service in the People’s Republic of China’ under ‘Security and Privacy’ was checked for factual accuracy that may have been caused by outdated information; ‘Outages and downtime’ was also fully updated.
