If you have a little cash to invest up front, then grab yourself a copy of
BlogsOrganizer
You install it to a subfolder on any of your domains, and use that admin panel to build ALL of your blogs (no putting up wordpress and fussing on constant updates, security breaches, etc), setup your trade links, setup any RSS feeds you want to use, can setup snippets to add in all kinds of information with a click, it's easy to adjust a wordpress template to use in it, and you write your post, and tell it which blog(s) of yours to post to, and when! You can also control any remote blogs you own that you built with wordpress and also any blogs you do on the Adult freehosted blog sites like SensualWriter, Sexusblogs, Thumblogger, etc. It's a total multiple blog management program for the serious Bog Empire builder.
