Question about removing/editing one's own posts

[White Dragon]

Sorry if this has come up before and I missed it.
I did check the Admin section but couldn't find an answer.

What is the policy on removing one's own posts?

A couple of times recently I have posted and then reconsidered my post.
Nothing addressed to an individual, but more along the lines of "I don't think this fits in this topic" or "Not sure people would find this interesting/relevant."

What is appropriate in such cases?
Do I remove it?
Do I ask a moderator to remove it?
Do I just leave a note in the post that says" Sorry, rethought my post?"

I removed them, but I want to double check that this was okay.
I thought there was a spelled out rule but I can't seem to find it.

The rule as far as I know it:
If somebody has replied to your post, don't remove it.
Otherwise, you're probably okay - the main reason mods don't want people to remove posts is to avoid the "swiss cheese" effect on threads - which isn't a problem if nobody has replied to yours (and especially if you've only just posted it, so few people have even seen it).
Never remove the OP of a thread.
