Vba dynamics or just a forum for article ?

[lovevn]

I would like to ask for your ideas about the following thing:

I am buildng a new site. It contain a forum(using vbulletin), classifieds (using photopots classifieds).

Plus the above things,I want to have an aritcle zone, a download zone. My question is should I use vba dynamic(which let me install as many copy as I want with its multiple license) for article and download or should I just creat a category in my forum and use it as article zone, and creat another category for download zone?

I think that the site would look professional with vba dynamics but vba dynamics will take time when upgrading in the future

Anyone has idea please let me know
Thanks
