I know I was just…

I know I was just here, but I need some advice/volunteers. Needed Advice: What is the best way to have a “guest blogger” on my site? Should I add them momentarily to my people-list-do-dad? Have them email the post and publish it myself and put their name on it?
Now for volunteers: does anyone want to do a guest post on Lordofthetrekkies? It can be about anything (we~ll, not anything you have to keep it PG and free of political/other grown up-ish stuff).
Thx in advance! 😉
