The blog I need help with is codydehaan.com.
I imagine it is possible to do this with PHP, but does WP.com offer (or is there anything that can be used) to do something similar with WP?
No I’m afraid there isn’t. However, this can be done on a free software install from wordpress.org. >
Understood now. I don’t have an answer for you, hopefully either another Volunteer or Staff member will have one.
I do know that all wordpress.com blogs do have RSS feeds and external site that are equipped to do so can use RSS feeds to display your wordpress.com posts.
