Changing admin folder name

After completely mucking up my website (my own stupidity) I managed to get it back up and running smoothly. I had to do a clean install and the admin folder name is the one given during installation. I'm hesitant to muck up my site again so I'm asking if it's ok to simply rename the installation admin folder name with a simpler one. I thought that I've done this in the past with no problems but having spent 2 days trying to get my site working again, I'm gunshy to do anything.
Thanks

Yes, simply rename the folder and you're ready to go.

thank you
