Is it possible to share a document library between subsites?
For example, I have a document library (doc_A) under the subsite (site_1). I want to share this library with another subsite(site_2). So, if a site_2 user add/update/delete any file/folder within the doc_A, the changes must show up on doc_A under the site_1, since it is the same document library.
Thanks in advance.
