Hi there. Welcome to Wikipedia! I noticed that you didn't have a welcome message yet. The welcome message has some links that you may find useful.
If you want, you can drop us a note at Wikipedia:New user log to introduce yourself. Before you start doing a lot of editing, you might want to take the Tutorial. It gives a lot of basic info you'll want to get you oriented on Wikipedia.
I see that you have edited the section on pentosan polysulphate treatment of Creutzfeldt-Jakob disease. The content of an earlier version of the article was found to be incorrect by the Nature review (December 2005). Please see Wikipedia:External peer review/Nature December 2005/Errors for more information, if you are not familiar with the Nature review.
A link to the manual of style might be helpful to you. It contains information like how to include quotations in articles. Also, verifiability is a good reference for content of an article and how to cite sources of information. No personal attacks and assume good faith can help you work with other editors.
If you have other questions about the project, check out Wikipedia:Help, or add a question to the Help desk. You can also leave me a question on my talk page. Best wishes, --Walter Siegmund (talk) 23:20, 7 February 2006 (UTC)
