I am an academic living and working in the north-east of England. I've always lived in the region and have spent time in Durham, Sunderland and Newcastle. I work within a University Law Department and teach a variety of subjects related to English Civil law. I'm still fairly new to Wikipedia, but hope to become more familiar with the various techniques as I go along.
The encyclopedia proper is the main namespace and contains all of Wikipedia's encyclopedia articles. All of the other namespaces have prefixes, which must be included (followed by a colon) at the beginning of links to pages in those namespaces in order for those links to work. Otherwise, the links will point to the main namespace, which has no prefix.
Currently, Wikipedia has 30 namespaces: 14 subject namespaces, 14 corresponding talk namespaces, and 2 virtual namespaces.
