In regards to employee center timesheets... does anyone know of a way to limit the users ability to report time to the time they have been allocated? Meaning to say I have estimated 10 hours for a task, as it stands the users can submit unlimited to time against the task and NS just increases the estimate to match the time submitted. I am needing to prevent the more then 10 hours being submitted without first approving it? Does that makes sense?

it does make sense but unfortunately i don't think there's a way to limit it. usually it's more of a pain to get people to enter time at all, so i think NS errs on the side of not preventing time entry. you could probably do it with a script?

I agree with you on this. I have a client who is looking for this very intently. I am thinking a script is the only way but I am also not 100% sure I can ensure that script would execute on the customer center.
