I have an aged PR3 domain. I've owned this domain since it was registered, so it's not a question of buying a domain, but I am repurposing the domain. It has had an eCommerce store on it, which is not doing much, so I am taking the store down and putting up a wordpress blog which I am going to use in a blog network.
I have hundreds of incoming links to this site and plan to set up redirects so that all the incoming links resolve to new pages on the site.
Is there anything else I need to think about doing in order to maintain the site's PR?
