I'm researching moving the following site to WordPress: http://nhand.org/
However, I need to be sure I can add two features to the new site before I make this decision:
1. Ability to take credit card payments on the site (for dues and for the annual conference).
2. Ability to have an interactive calendar where doctors can post talks they're giving.
Please advise if you know whether this functionality is possible and how to go about doing it.
Thanks in advance!
