I hope that's not the the entire community, as it is a small exclusive group that, from what I've read automatically drops people after a couple of months.
I know.. Still, to me Phoenix is a much needed visual update of osCommerce with PHP 7 support, rather than a different product. The file structure is the same, database is largely the same, etc. I could be wrong, that's just my own lowly opinion, whatever that's worth.
You are right, it is not restricted, just not readily available here. I couldn't find any upgrade information on this site/forum, and it seemed odd to me, hence I was just trying to give feedback, maybe even help others that may find themselves in my situation. In any case, I am sorry if my post irritated anyone, especially people that contribute their time and expertise to this product. It wasn't my intention at all.
