Oh, sure, I can help you out there anon.
First of all it can’t be your main blog. So you have to make a main account (or use your existing one) and then a secondary blog on that account.
To do that click on your little person icon in the right corner and in the dropdown menu you’ll see ‘blogs’ as a heading- directly NEXT TO that heading (not under the heading as most things would put it) is ‘new’. From there you should know what to do to make the blog I am assuming.
Now that you have that blog page, the one that you’ll use for having multiple people on a blog, click on the person icon again. Now click on your new blog’s name in that dropdown.
Then click the person icon AGAIN and now it’ll show a menu of options for that blog in particular. There should be an option for ‘members’, so, click that.
It’ll take you to a page to, of course, add members. You do that by typing their e-mail at the top next to the ‘invite to this blog’ button.
If I recall as the blog’s maker you are automatically an admin. All other new members will be regular members unless you promote them to admin. Idiotically there is no moderator level, which caused this blog a lot of trouble a good while back.
But I digress. Admins have some more privileges of course. At the moment I’m not sure I remember each one but I’ll list them here for convenience…
Access To The Blog’s Inbox
Viewing Queue/Draft Posts
Editing Other Member’s Posts (Also deleting if I recall)
Ability To Remove Regular Members
Can Not Be Removed (Even by another Admin, which is where we had a problem on our blog)
Regular members can still make posts and schedule/queue posts but that’s pretty much it if I recall. It’s also worth noting that queuing a post can not be viewed by them even though they can make them. So an admin would have to check for mistakes.
Speaking of, when queuing posts, the sub blog has it’s own time settings. Each individual’s time zone doesn’t matter when scheduling for the blog, the blog’s itself do. For example I’m in the Eastern time zone, so, I have to make sure to schedule everything an hour earlier from my own time since the blog is run on Central time.
I think that’s probably MORE than enough info, but I wanted to be thorough. Good luck with your multi-person blog anon!
