As I am sure some of you will have noticed from my posts I am a complete noob when it comes to running websites, but I am learning fast. I started my site in 2009 with a default vB3 install & vbAdvanced as a front page, upgraded to vB4 last March thinking it offered everything I needed (yeah, right) and started using a lot of add-ons, but things kept breaking with upgrades, so I somewhat lost interest in using them as I couldn’t keep up with it all. Now I am starting to build the new site, with xF & Contentteller for CMS, and I am looking at a growing list of cool add-ons here, but I am a bit nervous about using more than anything absolutely essential because of my experience with vB4, I don't want to install lots of nice features for users only to have to discontinue them later. Now I seem to remember reading that the way xF is structured and because it's built new brand from the ground-up instead of being an ABC* job, upgrades shouldn't break add-ons so easily. Now, I understand, there's no absolute guarantees and that some times things will break from time-to-time, but I guess I am just looking for some reassurance that it's unlikely to be such a major headache. So, is my understanding about right? * ABC = All Bits Combined.
