One word about forum. When I switch from my old code to YSE, my users start complaining to MyBB forum immediately. They were used to standard inbuilt forum and do not want new one. As I had no choice on this time, MyBB forum stay on site, but I see so people use it not so willingly.
If it is possible to reinstall old type forum, it will be wery interesting for me. Actually I have copied forums.php and some other files from my old code and made necessary changes in DB. Old type forums works, but what to do with all files of MyBB forum as they are not necessary now? How I can safely rid off all unnecessary files and DB tables of MyBB?
