**Xi Yin** : I will review the formulation of closed (super-)string field theory, its application in string perturbation theory, RR flux backgrounds, D-instantons, quantum string vacua, and discuss some future prospects.

**Ted Erler** : We review a body of work, following the formulation of Sen's conjectures in the late 1990's, which endeavors to realize D-brane systems as nonperturbative vacuum solutions in open string field theory. We first sketch solutions derived numerically in the level truncation scheme, and later analytic solutions. If time permits I will sketch the status of analogous questions in closed string field theory..
