I had a few questions that somebody could probably help me with, I planning to start a business-to-business website, My Company will create an Internet network environment for small and medium sized companies in developing business relationship between one another. To keep it simple, it’s going to be like a Business network site. I’m in the process of developing the website, and I want to implement membership capabilities such as, having member register, personalizing they profiles with their company details and have a place where they could post to an online catalogue. Kind of like a forum. Does anyone know of a membership platforms that offer these types of capabilities? And if so, Can I implement this type of platform after my website has been created, or does it have to be implemented when creating the site?
