Which CMS can implement dual registration?

Question

CMS

Good day to all.
As part of the course work, you need to make an Internet conference site in CMS. It is necessary to implement two registrations on the site (one for viewing the bank of articles and the possibility of correspondence, the second for registering at the conference). Actually the question is: in which cms it will be more convenient to implement double registration and what difficulties should be expected?
Thanks in advance.
