Free Softwares for download for Blogger

All bloggers require softwares for blogging and places where one can download these free softwares are
download.com
freedownloadscenter.com (one gets a free sotware on this site every day which is othervise a paid software)
Two softwares which have been particularily liked by me are blogblaster which sends a ping to all search engines that the site has been updated. However its free version only supports maximum 2 blogs.
Another software liked by me is Allscoop RSS submit pro which is free version and it ensures automatic RSS submission.
