Question - Where can I edit staff contact details?
Answer - Select Admin>Personnel>Staff. From there, browse for the member of staff by clicking on the drop down box. You can then start typing the staff member's name and select their name as it pops up. Once their record has opened, click on the "cog" next to their name (above their photo) This will present you with their "personal details" where you can add/edit details.
Also under Extra Details click Contact information, this is where you can record their emergency contacts/next of kin.
