Okay, I don't know if my approach is correct, and hence I am running into some problems.
I installed a session of wordpress to the root of my website to have my random blogs on there. I tried creating seperate pages for other, more specific subjects (travel blogs, business blogs), but I couldn't add any more blogs to those 'pages.'
I then decided to create other installations of WordPress. So, the main page has one installation and the other sections of my website have seperate installations. So, when I edit something, I have to do it 4 times. When someone registers, they have to register 4 times!
It might make more sense if you check out the site, http://www.ihavetoblog.com
Is there a more simpler way of doing this?
