From the main page, after you select the Bioscience Forum, and then the Medicines and Diseases Sub-forum,
it is possible to have the entries sorted by Recently Updated, Start Date, Most Replies, Most Viewed and Custom.
However, when you choose a tag word, the selection of sort options are Last Update Time, Title, Replies and Views.
There is no Start Date sort option with tag words.
Sorting tag words by Start Date would be a useful feature. Sometimes topics from years ago displace recently posted
topics, as the default sort is Last Update Time.
