Do you know that all Yahoo Groups have an RSS feed. I noticed this while I was visiting the UOR group.
The RSS link is very standard and you can easily guess what the RSS URL of any Group.
http://rss.groups.yahoo.com/group/YOURGROUP/rss - Just changed the word YOURGROUP with your group name. This is a nice innovate idea from Yahoo. Google Groups 2 which is now in Beta stage already have such a feature. Now you don't have to keep visiting their site to see if someone has replied to your post.
PS: I just saw that Indian Institute of Technology (IIT) Roorkee, formerly known as the University of Roorkee, is planning to set up a centre of excellence in the areas of nanotechnology and nanosciences within its campus. The institute is also exploring the possibility of setting up a centre of excellence for transport engineering. This is great news.
