Incompatible with multiple authors plug-in?

I’ve installed the multiple authors plugin and would also like to use the subscribe to comments plugin as well.

When I activate the plugin and set the text for ‘subscribe’, ‘already subscribed’, etc. I don’t always see the ‘subscribe to comments’ option with each blog post.

There is no rhyme or reason to it either. It could be a post with a single author, one that I’ve written, one that another person has written, or anything.

There are posts with multiple authors that I’ve started and those that I’ve contributed to, and the subscribe option shows up. It doesn’t seem to matter if there are comments already or not.

I’m also seeing the ‘you are already subscribed’ text for posts that I have not yet subscribed to.

Any thoughts on this?
