I am considering integrating a WordPress blog into an existing site. My only concern is that the site has a very large community and I need WordPress to work seamlessly with this community.
All of the community members have their own profiles. I would need the users to be able to log in to the existing site the way they've done in the past. Then, after they've logged in, I would like them to be able to comment on the blog through their existing username (I do not want them to have to sign up for a new username). If they comment on the blog, I would like other users to be able to click on their username and be transported to their current profile.
Is this possible?
