I have seen people create blogs with some blogging site and they do not get the flexibilty they need.I will help you create a blog with wordpress for free on subdomain. Wordpress gives you more flexibility then a free blog site. I will maintain the site for you for free. The idea is still under testing it all depends on how many people will be interested in the start.I will also install wordpress for you on the server. there will be support provided for almost any thing. THese applies for people who want to create forums as well.Anyone interested can PM me.
You're opening up security risks doing so unless using a completely different database for each blog/forum.
there is nothing like that. All will be different website. If you have your domian great. It will be a seperate wordpress installation for all of them
Honestly... that's a BAD idea. I launched a site like this last December. www.conservablogs.com It has been a complete nightmare. We have about 50 very active bloggers who have a lot of freedom and access with their blogs. The problem is, giving them that kind of access present problems that wouldn't happen with a Wordpress MU install. People edit files that completely knock out their blogs and I have to do backup installs. People put javascript and other stuff in the sidebar and header, not knowing it will mess with the site. And that isn't even the beginning. The next major part of the headache is the updates. Every time WP comes out with a new version, I have to go in and update 50+ blogs. And believe me, not all templates like updates. Nor do all plugins. So while it is a novel idea, in the end it's just too much work. Wordpress MU is MUCH better. I just launched my first WPMU site (www.blogaught.com) and it feel like a corvette compared to the sluggish old boat that is conservablogs.com Just sayin...
