This site is designed to be interactive. We strongly encourage participation in a variety of ways.

1. Comments: Please feel free to comment on any of the CAT's through the forum page. We hope to stimulate some lively debate about the merits and implications of the research reported.

2. Notice of missing studies: Please let us know if we have missed a (your?) paper, by posting the reference in our forum. Alternatively e-mail the article direct to Mike Bennett.

3. Write a CAT: If you are aware of a study not yet reviewed, an alternative to (2) is to e-mail your CAT for editing and posting. Proper acknowledgement will, of course, be made of your work.

4. Problems: Finally, please notify us of any problems with the site, or when you note a CAT is out of date. This website is an evolving project and will benefit from your thoughts and suggestions.
