A common question:

###I want to contribute to Public Lab -- should I post a research note or a wiki page?###

And one possible answer:

**If in doubt, just go ahead and write a research note.** You can always copy it into a wiki page later.

###What's the difference?###

**Research notes** are just like a blog. You are the author, and they have a publication date. They can be informal -- just a photo or a link -- or regular updates on your research progress. 

**Wiki pages** are collaborative documents. They're more formal and complete descriptions of projects, instructions, or anything structured *you want others to be able to edit and correct*.
