Can secondary accounts have different email addresses?
Yes, please. I have several e-mail accounts and several DW accounts to keep things neatly organized and easier to manage. I would see no point in linking my accounts if it meant I had to give up on keeping my e-mails organized.
Creating a secondary account should require an invite code?
I don't see why not.
2)She'd like to be able to subscribe to some other journals via her personal journal, and some via her work journal (so that her mother never knows about them!). But she'd like to read them on the same page – one central reading page. She'd still like to be able to filter, though – for her fiction, sometimes she just wants to read fic_annabel's reading page.
I would hate to have the central reading page as a default. Again, I keep things separate because it makes it easier for me and would not link accounts if I couldn't decide how separated I wished them to remain.
4)She'd like a link to the fic_annabel journal to show up on the profile for dw_annabel, and vice versa, as being her journals. But under no circumstances should her mother be able to discover a connection between dw_annabel and work_annabel!
I'm not sure what's suggested here but I'd like to have the same privacy settings for this as for other profile elements (everybody, registered, access only, nobody).
When she goes to leave a comment in she needs to be able to choose whether it shows up as a post from dw_annabel, fic_annabel, or annabel_work.
Sure, but I don't think she should always have a choice. Let's say fic_annabel's on my Access List and I've posted a locked post. I only want comments from fic_annabel, not dw_annabel. I may not know who dw_annabel are and seeing a comment from this stranger on my Access Only post could scare me and make me go straight to Support... unless there's a way I've been made aware the two accounts were connected by fic_annabel and given them explicit permission to comment on my locked posts with either account (and have a way to remember who's who otherwise it could get hard real soon).
