There are already topics about this but they either have dead links or the php plugin doesn't work, etc, etc. Also, none are in the How-To and Troubleshooting section, which I really think this belongs in.
It seems obvious to me that if there are multiple authors, and if an author is logged in, that that author should be who shows up when posting, not "Anonymous". There shouldn't even be the Name/email/website form available to fill.
This should also make it so that the author can edit his/her own comments, but that's a feature. The having to manually type in your info even when you're logged in is a bug.
What I'd like (for now) is a workaround (and eventually it to be fixed).
Many thanks, and I'm sorry if a real, working answer is already in this forum and I just didn't find it.
