Mambo Polish up, with some php code.

Wanting a php programmer to polish up our mambo based website and specifically clean up the calendar script of errors, remove news feeds left lying around the site, and to correctly set up a back end editor interface so clients can log in and post/edit their own files, news, events, and newsletters. A newsletter section will also need to be added as a seperately linked (from top bar) news item style, similar to front page. The captcha at signup and download is not functioning and would need to be fixed. These modifications should not take very long for a skilled mambo user. For further details, please ask. Max budget of $50.00 aud Website is http://lcc(dot)edu(dot)au
