Once I reach 5000 documents can I still index a column or change permissions if I have created several views that will always keep me inder the 5000 item view threshold...
if overall I have 5000 items regardless of views will i have issues indexing columns, changing permissions, etc.
From Greg Sharepointmaven
"it “locks” the document library from trivial operations like adding columns, making certain adjustments to views, setting permissions, sharing and even managing column indexes." http://sharepointmaven.com/how-to-overcome-sharepoint-5000-item-limit-threshold/
