Hello - yes! You can change which Adobe ID is linked to your Behance account here by clicking "use a different Adobe ID." This will also be the new email address you login to your Behance account with: https://www.behance.net/portfolio/promote
Hello Sarah, I have had the same Adobe ID forever, yet I have 2 behance sites and I have no idea how to merge them. I want to keep my original URL which is now unavailable as my first account is using it.
