If you are using WordPress version 2.7 and need to update to version 2.7.1, try using the automatic update. All you need to know is your FTP info. No more needing to download the update and FTPing back to your server. This feature appears to be working very smoothly.
Also added with the 2.7 version is the ability to upload Plugins via the admin. You don’t even have to unzip your files anymore, it’s all automatic.
Just two more reasons why I am a huge fan of WordPress.
