I was actually thinking about this, but couldn't find your other thread to post in it.
Would a divider containing (in your example) "Effects by Industrial Light & Magic" be a breach of the rules as they currently stand?
The rules give us very little guidance about the use of dividers, but I've always thought they were to be used to separate different credit lists from each other. In your case, you have a group of FX credits separated from the rest of the crew credits by the use of a header: Effects by ILM
It's possible, sometimes even likely, that there are other companies involved and so using your example you could have:

Divider: Effects by Industrial Light & Magic
XXXX Visual Effects Supervisor
XXXX Special Effects Supervisor
XXXX Digital Effects

Divider: Effects by Weta
XXXX Visual Effects Supervisor
XXXX Special Effects Supervisor
XXXX Digital Effects

So to me, they are separate crew lists, and separating them with a divider seems perfectly logical.
And again, there is no restriction on the contents of a divider in this situation so mentioning a company name seems fine.

So maybe all we need is a tidying up of the rules, making this explicitly allowable, but to be honest I can't see a rule that currently specifically prohibits this.

That only refers to credits, not dividers. A divider isn't a credit.

So "20th Anniversary Edition" is a credit? "Episode 1" is a credit? 
They're not credits because nobody is credited with anything!   

(see, I know where the rolleyes emoticon is too  )

Given that I'm not contrubiting any of this information I am curious about the reasons behind the NO votes.

I really would like to know what the negatives are of allowing these dividers? Maybe I'm missing something.

You see, that looks good to me. Everyone gets their credit, but they are organised and separated so the information becomes readable and more useful.

I recently submitted some crew changes to Sleepy Hollow and I have to admit part way through the end credits I simply gave up on listing the visual effects credits because there were so many of them and the list was becoming so long and meaningless.

Looking at that I might go back and see what it looks like if I add in the company dividers as per your idea.

My no vote is because currently you can't cross-link a divider, which makes it useless for looking up all the ILM credits for example.

That, to me, doesn't make sense. You can't currently cross-link the data, so you'd rather not have the data there at all?
I'd rather have the data there so at some point cross-linking may be introduced.

edit: just seen your edit. I guess if it's data that doesn't interest you, I think it's fair not to expect you to say "yes" to it.

Pantheon, have you done this already to any of your titles?
It might be helpful in the debate if you could actually point to a specific title so we can see an example at work.

Yes he has...he posted this in his other thread.

Have a look at my online collection (and find Charlie and the Chocolate Factory) to see what I mean.

I like it...the word wrapping could be handled better...but, other than that I like it as it makes the data more meaningful.

Thanks for that Unicus, because he didn't have the icon on his posts I assumed he hadn't made his collection public.
I think it looks great - very tidy and organised and legible. Just to give people an idea, this is what the same Art section would look like without dividers:

Nick Davis: Visual Effects Supervisor
Gabriella Pescucci: Costume Designer

That, to me, looks much worse and makes the information harder to read.
@Cubby,
I don't see that as a huge problem. Ideally we'd need to see it but I don't think it would look any worse that what it would look like without the extra dividers. And I don't see a problem with mentioning ILM twice if they worked on the film twice.
