I've just checked in a couple of little changes to DasBlog, hopefully these will benefit others too:
Fixed the access denied problem when using any web dialogs on the AddEntry.aspx page. (Code was trying to load the SiteSecurity.config file from the wrong location, which always resulted in failed authentication)
This problem was preventing us (Numerica) from inserting images and formatting code, and I suspect only occurs when Windows Integrated Security is being used (as thats the only time I've seen the problem)
Added "Author" to syndicated content, the value is taken from SiteConfig.Contact, which is typically an email address (as recommended in the RSS2.0 spec).
I'm hoping this wasn't originally omitted for any particular reason.
I'm aware that there is a recommendation that the author isn't included when the syndication source is a single authored weblog.
Perhaps I should change this to be the login name of the person who actually created a post, to allow for multi-authored blogs. Having said that, the rest of DasBlog isn't really geared up for that (one only has to look at the configuration options to see what I mean).
