I just went thru the experience of installing WP, then having a bunch of files not work properly, because I didn't enter a full (absolute) URL when asked for my blog's URL during installation. I typed mydomain.com/myblog, instead of http://mydomain.com/myblog.
This was a stupid mistake on my part, and I should have known better, but many users will not. I had to uninstall and reinstall WP to fix the problem. So...
1) Was there an easier way I could have changed the value of my blog's URL, without reinstalling?
2) Could you clarify the prompt during the installation procedure, so it says something like "Please enter the full URL for your blog, including http://"?
Thanks for creating such a great program!
