Yep... that was the thread where Gunter, myself, and others started talking about what could be done.
Everything, on the latest release of ADDT, worked until 5.2.10 (which really was the release candidate for PHP 5.3). So, if your server runs 5.2.9 or less, you will be fine.
Not sure what your hosting situation is but if they do regular updates like my hosting company does (Little Oak), then I would start making plans to get your stuff converted right away.
It took me over a day to figure out what went wrong on a client site when the switch to 5.2.10 happened and then after testing and testing, I had to recreate the registration system using my WebAssist tools (thankfully, I had them). So, I recycled what I could from the ADDT stuff but really had to write a new reg system using Data Assist to input the data, Security Assist to authenticate users, and Universal Email to send confirmation emails. It also forced me to learn a lot as I ended up creating my own random key generator for added security amongst other things.
I actually ended up writing a set of functions to handle things like date reformatting for databases, another function that would analyze a birth date and test it to see if the person was at least 13 (for legal reasons), and an encryption function (I needed this because I started with ADDT which uses MD5 and WebAssist uses SHA1). But the end, I now have a far more comprehensive set of functions that I can use on any site... so the end was good but finding and fixing the problems was quite difficult (especially when the client's users couldn't register or login for over a day).
