Thanks for your comment. You can create an unordered list by using stars (*). Example:

foo
bar
foobar
x
y

Ordered lists are also available.I know that certain things on WP might indeed be a bit difficult to find out. For example, it took me a year to discover that it was possible to create a wikilink to another wiki (like this). Another hint: google Wikipedia: it sometimes works better then the standard searching. Ask me if you have another question. Cheers,
