>Hi all
>
>I was under the impression that if a firm has a min. of 2 MSCD employeed than it's product can use the MS Logo as a Certified Product, is this correct?
>
>In such a case what are the responsibilities of the MSCD professionals and the firms' towards the product? What would happen if one or both leave the firm, does the MS Logo still be valid? Are there any payments to be made to MS for such? Will the cert. be valid for Vista? Are they supposed to be one each for XP, W2K?
