I am using the wordpress hosting, so there is limited options to hack code and there is no option for importing external plugins and themes (sucks), but it is free.
There is "Subcribe to this blog" RSS feed button as default on the top of the right side bar in the "INove by mg12" theme. You can subscribe through igoogle, yahoo, etc.. but I am missing lot of other subscription sites?
If you look at a super plugin "Add to Any" http://www.addtoany.com/
Anyone know a solution to this?
