Often after I have closed a project, a client will want to add an additional comment or up-load a document, but they are unable to because the project is closed. They end up emailing me directly and that works, but takes away the benefit of their comment or document still being tied directly to a given project or task. Additionally, there are times when a project is basically complete and I would like to close it to get it off my workflow, but there could be a small open client task that the client can still work on/complete after I close it. If they could still work on their task after I close the project, it would benefit/cleanup my workflow without having to either re-assign the task to the next project or to keep the project open and have so many projects clogging up workflows.
