When composing outgoing posts in Hootsuite, what's the best way to collaborate with a team or team member to finalize that post?

Publish the post to a social network, then click 'assign to team or colleague'.

Save the post as a draft and then add it to the collaboration board for that team.

@Mention the team or team member in the drafted post before saving.

Assign the post to a social account the team or team member manages, then click 'Save Draft'.
