These days most research centers and associations have web sites, blogs, subscriber news lists, and other means to keep researchers informed about opportunities as they become available. This is a great way to learn as soon as possible about conference calls for papers, special journal issues, as well as funding and job opportunities. Ask colleagues who work in your research area about relevant subscription lists and web sites. When faculty members send you emails with information of interest to you ask them for the source so you can receive the information directly. You can either add your email address to the subscription list or add the website to the web clips option on a Google sidebar, for example.
If you visit the Penn State Research Population Center you can subscribe to receive ADD Health news updates or you can add the Add Health update website using Google web clips. The Penn State website has about 40 separate data sources so it is well worth a visit even if you are not using the Add Heath data set.
