Are there any risks associated with a collaborator adding content whilst a designer continues to make alterations to the site? I'm assuming that as long as I don't change the structure of the collections this should be alright? If so are there any best practices? Would it be advisable to ask them not to hit 'publish' for example?
I assume this too.
That would be a good idea but there is no real risk as they can't publish the design changes you're making.
I don't see any major risk to have a content editor adding data to a site you're working on. Only risk of loss is if you're deleting fields from a collection settings, this would probably delete the datas of this field.
Thanks Vincent. Seems to be working alright so far.
