I received two types of questions

• The first type are generic questions, about how the site works, and general theoretical questions. I will post theses questions and answers on my StatTools FAQ page
• The second, and much more common type, are feedback and questions related to specific project, requests for assistance, sharing of of data, asking for advice, or discussing a specific issue. These are not suitable for posting on FAQ, and each occasion requires a response via the email. It is therefore essential that a valid return email address is provided or I will not be able to reply.
