So far from what I can see of the second release candidate of bbPress 1.0, it looks like integration has gotten better for BuddyPress and WordPress MU, but don’t expect a simple turn-key installation. There are simply too many configurations to not have to dip into the wp-config.php or bb-config.php files a little bit.
Integration of bbPress1.0 RC2 is essentially the same as the Alpha’s, other than there being a spot to enter the ID of the main WPMU blog. There’s also an extra variable to add to the config files to force the integration method, but I suspect that to be only temporary.
Once everything becomes 1.0, things will probably make more sense and come more into alignment.
actually i dont mind get the trouble in first time installing things.
my actual concern is when it’s time to upgrade.
will the upgrade smooth? or everything fall apart and we need to build up each pieces together again??
As long as you’re not modifying the core files, everything should upgrade gracefully.
