and just to set things straight. installation of phpbb takes at most an hour and that is only if your hosting is setup very strangely.
it is only 4 steps;
1. download the phpbb files from here to your computer
2. unzip and upload them to your server
3. create a database using your hosting control panel
4. go to the install page where you uploaded the phpbb files and click buttons and fill in the blanks.
you can't compare what you have been doing to a normal install and operation.
you have been trying to use phpbb is ways that it was never intended to be used.
you have been trying to use out of date styles
you have been trying to do these types of things on free hosting
etc, etc. etc.
not exactly what most people do with phpbb.
also, compared to the total number of phpbb users around the world, then number that come here with problems is very very small.
Some of the things you think are such great additions like the WYSIWYG editor, I find completely a waste of time and space in a bulletin board.
point is that like the old saying goes " beauty is in the eye of the beholder".
go to mybb support and ask them which is better and why. I seriously doubt you will find anyone that will tell you phpbb is better.
