It might have been pretty horrible but I hold Frontpage 97 with fond memories, it started my IT career, although not for HTML reasons.

The _vti_cnf dir left /etc/passwd downloadable, so I grabbed it from my school website. One Jack the Ripper later and the password was found.

I told the teacher resposible for the IT it was insecure and that ended up getting me some work experience. Ended up working the summer (waiting for my GCSE results) for ICL which immeasurably helped me when it was time to properly start working.

Did think about defacing, often wonder that things could have turned out very much differently!
