There is actually a website devoted to Wenglish, but whoever put it up hasn't included any content yet, so it's a fairly pointless exercise. Perhaps at some point it will be of some use, though; it is at http://wenglish.org/.

More useful is http://talktidy.com/about.html, which, though not well designed, does contain a glossary which can be accessed via the alphabetical 'buttons' at the top of the main page. It mentions two books which you might perhaps find helpful: Talk Tidy and More Talk Tidy, by John Edwards, who reckons to have coined the term 'Wenglish'.
