Working Collaboratively

Good morning from delightful Galway.

I am a student completing a BA in Digital Technology. I am part of team creating a portfolio website which will be marked for our assessment.

I love Local by Flywheel and have already almost completed a website on it. For the student project I need to collaborate with my team, invite them to view the site (which I know how to do!) but can I invite them to edit the website as we collaborate.

Secondly, just thinking out loud. When we submit our assignment, we have to submit a link to our website presentation. This would mean my website would need to be accessible at all times for the assessors. I am wondering would we be better going live in advance of submitting the assessment. What would you recommend? How long would it take to get hosting and go LIVE?

Regards, Elodie
