Free membership gives you access to the SAS Skills Discussion Forum for non-programming questions about SAS. Programming and Recruiter memberships, which require monthly low-cost subscriptions, give you access to the same forum and to the SAS Programming Forum, where you can ask SAS programming questions. However, all questions and answers are visible to all members with access to each forum, which may not be quite what you are looking for.
To fulfill any need for confidential correspondence you may have seen a recent addition to the blog menu. The Premium SAS help desk service, called [sas.answers @ Holland Numerics] (which has actually been around since 2002), is different. It does not require even Free membership of the blog, but it does require a separate subscription payable using PayPal. What makes this service special is that it provides an in-house web-based interface for you to ask questions, which automatically generates an SMS message and an email to Holland Numerics, with a copy of the email sent back to you too. There is also a service level agreement to provide an answer to every question within 48 hours, and that answer will be privately sent directly back to the sending subscriber! Please note that, if a monthly subscription is not necessary, then a single question can be asked instead for a reduced fee.
