I do apologize for the problems. The reason that you can't see the article in the edit probably is due to differences in the magic quotes in my setup. Just look in the edit and new article template pages to see what is different for the article form. One probably has aporeplac() and the other doesn't. Which ever one works use that one.
As for the author aspect I think this is a very good point. I do not plan to make any major modifications to it but it should be pretty easy to add it in the replacement tag without much trouble. The reason I am not planning on making any mods to it is b/c I am working on a plugin system so all these mods/hacks/etc can be easier to install. The first plugin I think I am going to use is a blogger plugin so you can use blogger to update the blog and since you asked (;) ) have different users on different pages. The reason for the blogger plugin is b/c there are standalone apps (gtkblog) that use can use on your desktop. It also uses the atom feed which is supported by many future blog systems so that way we get a really good crossplatform (movable type, blogger, etc) blogging tool that can be easily exported to rss/atom readers.
Of course I am ultra busy at the moment so things are going kind of slow (three jobs and full time school

) but things are still moving along. I have already used phpwcms on three different client sites I am doing and the results are very nice.
If you are still having really bad problems with my blog hack look for me online on aim (i0nr0ck) and maybe I can test somethings for you and see where I messed up things for you
