Forum for WP Blog

I have a WP blog and would like to have a forum board added to it. You should be able to integrate them flawlessly together so they share the same database and use the same cookie (so that a single log in will allow for access to blog and forum). Forum back end should also be integrated with WP back end so it all can be managed from within WP admin panel. Forum should also be integrated into the blog design so it looks like part of the website, not a separate entity and I would prefer for it to look like this - [login to view URL] I don’t care which forum script you use, as long as it is a stable script with options to subsribe to threads as well as replies and is built with fundamental SEO requirements in mind (H1 headings for titles, all images to have alt tag that matches title, etc). I will need few mods installed for the forum though: Friendly URLs – so all forum URLs contain keywords from thread titles and no dynamic characters such as “?” or “+” Rel Nofolow – all external links (leaving the domain) should have the following added to them – rel=”nofollow” target=”_blank” – all internal links should remain untouched. This should also apply to signatures Social Bookmarks – will need to add social bookmark buttons to forums as well I’m also using XML Sitemap plug in for WordPress and would appreciate if that was modified so that it gets updated with forum posts as well. Pinging service should also be notified when forum threads are started. I have tons of blogs that I would like done in the same fashion. Whoever can do one according to my requirements and for a good prize will get to do all of my blogs and make good money.
