Edit Limits adds certain limits to editing nodes and comments. This can set the number of times a node can be edit. This can also set a time frame for nodes to be edited, as well as a different time frame that comments can be edited.
Limits on nodes can be combined, so that a node can only be edit a set number of times or within the time frame.
Node edit count
Nodes can be limited to a certain number of edits before it is locked. This can be restricted to a subset of content types. Users with the "bypass edit limits" permission who edit nodes will not count against this edit count limit.
Node edit time limit
Nodes can be limited to a given time frame. When this is used, nodes can only be edited within the time limit set by the site administrator, starting when the node is initially saved. This can be limited to a subset of content types.
Comment edit time limit
Comments can be set to only be limited within a given time frame. Site administrators can set the number of seconds after a comment is initially posted before it can no longer be edited. Time remaining will be displayed to the user.
