is there a way to edit post titles after posting?

Yep. Go to your original post that you first started with, and edit it. Then you'll have the option to change the title.

I've never seen that option.

Edit-- nevermind... I just tried it on one of my older posts, and it worked. Thanks, Mac.

I didn't think that was possible either.

I snuck that one in a while back.

ah, there is a lag time between the post title and front page title updating. At first they were different which made me think it did not work, but then the front page title caught up. Cool ,it worked.

Any time that happens, try using CTRL+F5 to do a hard refresh on the page.

will do ,thanks for the tip.
