Pre-purchase questions

Hi

I’ve been using s2Member Framework to set up my website and like it’s functionality but have a lot of unanswered questions. I understand that you can’t support free members, and am happy to upgrade to Pro if I will be able to get assistance on the following.

1. I want my site to be a membership site, with 2 levels of membership – free and paid. The main aim of my site is to offer paid members technical advice via a Q&A. The way I want it to work is for paying members only to be able to view the Q&As, a paying member can ask a question but ONLY I can respond to the question.
Does s2Member support this, and what Q&A plugin would best suit my needs?

2. Subscription options: I want an introductory offer where new members sign up to a reduced rate for their first year, but to pay monthly. This will allow me to increase the rate after the first year. At the moment it appears that the Paypal options are for ongoing monthly subscription, without a fixed term.

3. I’m having trouble testing my site, as I can only log on as 1 user (admin). I want to be able to view the site as a visitor, a free member and a paid member. Is there a way of doing this?

I look forward to some advice.
