I have read your discoussion about dropping articles and snapshot creation and still have a few questions;
1. Is this true that after drop an article (sp_dropsubscription + sp_droparticle) I should create new snapshot, but if I create this article (table) on subscriptions- I can safely use my databases without re-initial? So this new snapshot is only for future reinitialize?
2. After drop and add an article- snapshot is usually marks as "invalid". Where (in sys views/tables) I can find info that snapshot is invalid?
3. Where (sys views/tables) I can find info that subscriptions is marked for reinitialization?
