Hi Macrocosm - I downloaded a copy of ACE explorer to test out your problem, and I noticed it doesn't support AJAX functionality. That can cause a problem with editing and saving new information. My suggestion for you is to log in via Firefox or Internet Explorer. I believe the initial registration problems could be solved by clearing your browser's cache, but since you've already successfully created a profile, that's taken care of. But try logging into WiserEarth via Firefox or Internet Explorer, and editing your About section. If that doesn't work, please let me know, and I'll do my best to address the issue.
