If this topic has been specifically addressed, I apologise, but I've searched and haven't been able to find a comfortable answer yet.
I'm new to WP; got 2.0.1; and kind of a newbie also, so please type slowly :-)
I've created a half a dozen new categories but have stopped short of moving old posts into the categories until I'm satisfied that the permalinks to the original post will remain intact.
In other words, if I take a 2 month old post called "Crappy Post Number 220" and move it into a category called "Crappy Old Posts", what will happen when people click on a link to the post from another blogger's page that references "Crappy Post Number 220"? Will they get an error, or will the referencing link still take people to the original post?
Not only do I wish NOT to inconvenience the other bloggers and their readers, I do not wish to damage my PageRank either. If that means having to leave my old posts uncategorized, then I guess I'll have to leave things as they are and begin categorizing from today forward.
Anybody? Thanks in advance for your answers :-)
