From this post How can I mark two responses as answers?, I understand that to keep things clear only one answer can be marked as accepted.
However,there may be kind of questions (like List of SharePoint development tools and Design Principles and Patterns in SharePoint) for which a real answer is combination of many answers.
Is there a way to mark the answers which contribute to the real answer as a whole? Also, does it make sense to start bounty for such questions?
