I tried to change the avatar of my profile here on the site (buddypress.org) but each time when I try to upload a JPG (small file size), I get this error in a red box:

“Upload Failed! Error was: Unable to create directory /home/buddypress/public_html/wpmu/wp-content/blogs.dir/1/files/avatars/4034951. Is its parent directory writable by the server?”

This is a known problem. The workaround for now is to upload it to http://en.gravatar.com/ Just do it for the email address that you used to register on BP.org and your avatar will be changed to whatever you upload to Gravatar.
