Too many domain names...

I have 3 domain names and I can hardly keep up with updating them all. I might cancel my other blog that has no domain name for now and re-apply later when I am finished with connecting it to a domain name. I want all my blogs to use a domain name with the exception of my journal that I have no way to use a domain name. Well, at least my journal has a page rank of 3 and that it is still the winner because it gets the big opps I need. I just wish my other blogs would have the page ranks I want. When can they possibly have any? I will give it time and work on putting my blogs out in the open for the search engine to find and rank them.
