Yes, no or maybe?
Is there any other place to get answers on this software?

By design there is no list of authors in b2evolution, but it certainly can be done. Just about anything *can* be done, but as far as I know it hasn't been done yet. Well, if it's been done then how to get a list of authors hasn't been shared is what I mean.

So yeah: it can be done.

The thing is you're asking a generic question without providing ANY information that would enable an answer worth typing. Is your blog in your domain's root installation or are you running it from a folder? What version are you running? Other than a list of names what do you expect your main page to be? Is each blogger blogging in their own blog or are they contributing across multiple blogs? Either way, are these names going to be linked to anything and if so what? Are you comfortable with reasonably simple mysql queries and file modifications? Got link?
