You deleted a large amount of text from the Glossary. Sometimes people not familiar with a Wiki do such things accidentally. No permanent harm was done: the version from before your deletion was restored (this is a built-in capability of the Wiki).
If you find yourself editing a page and don't mean to do so you can use your browser's Back button or the Cancel link on the edit page to leave the page without making any changes.
This is the discussion page for an anonymous user who has not created an account yet, or who does not use it. We therefore have to use the numerical IP address to identify them. Such an IP address can be shared by several users. If you are an anonymous user and feel that irrelevant comments have been directed at you, please create an account or log in to avoid future confusion with other anonymous users.
