Wasn't sure where else to put this and I don't want to tread on anyone's toes.
Is there a way to add releases that haven't been done by any particular group?
When I try to add them to the database, it says I must specify a group.

Quote from FAQ

All releases must have an associated group that is in our database.

Sidenote-
Most of the time if you have a question about the site you can find an answer in the FAQ or Forum rules. If not it's says in FAQ you can PM lambchopsil. (That's quoting from FAQ [url]http://mangaupdates.com/faq.html?cid=1#item36[/url])

There's also this thread - Random Questions "Attempt II"

I hope that helps for next time.

Yes yes, I know I make longwinded comments, but that's just me >.<
I should proof read my comments more, but I won't...
So keep in mind I'm filled with typos
