The site will be mainly an information hub where people can comment on nearly all of the pages. I want to have a big section of the site for information and then have a forum and blog so my first question is:
1. Has anyone integrated cmsms with a forum like vBulletin, FUDforum or PHPBB so that users of the site can comment on pages on the cmsms site and also post to the forum with the same login?
2. I presume vBulletin is the best route to go for a forum? ( A free alternative like fudforum or phpbb would be good too if people feel these are good enough platforms

3. Company Directory - Is there a limit to the number of companies that can be added? Can company directory be used with pretty URLs. eg www.domain.com/area/category/business-name.
a. I want to have a section on the site that will list 10 areas to start (probably grow to 20) and in each area the businesses would be listed like http://courses.itsligo.ie/.
b. Each area would potential have 100 to 200 businesses which would have their own page that will display info about the business and then people viewing the website can leave a comment about that business if they want.
4. Can the Blog module be configured to offer as much as WP as I would hope to be adding a blog post about 5 times a week or maybe more and it would hopefully be an active blog.
5. CGFeedback - Is there a limit to the number of comments this mod can handle? Working on guess numbers here but if every company got one comment thats about 20 x 150 which is 3000 before any of the comments on the blog.
I know these numbers are ambitious but I'm trying to think long term as the Sligo website is completely built on WP and I'm not sure if I should look at it this time. Would rather stay with CMSMS as I've used it a good bit now and really like it.
Any help on this would be greatly appreciated.
Thanks,
Paul
