We are continuing the long process of adding more and more conferences and different conference niches to our database. We are up to nearly 200 now with a lot more to go.
One of the recent feature requests we had was to be able to subscribe to different conference categories and be notified when new conferences are added. It was great suggestion that has now been implemented. Next to the Title on each listing page you will now see a feed icon 
which you can click to subscribe in your preferred RSS reader. Thanks Martin for the suggestion.
If there is any new feature or category of conferences that you would like to see please let us know.
