Thank you @mercime.

A small follow-up question on user sign-on/registration. As you clarified, there is a unified login for all wp and bp/bb components. Does it mean that the user profiles (wp profiles and bp extended profiles) are also unified/sync’d?

With regards to the twenty twelve – Buddypress compatibility, let me elaborate my set-up a little.

Twenty twelve is not compatible with buddypress out of the box (like bp-default theme is), so one needs to use bp-compatibility-pack plugin (or can be done manually) to copy-paste buddypress specific .php templates and other files to the theme directory. This also includes buddypress style sheet (bp.css) which seems to be a copy-pasted part from bp-default style.css.

Thus, when you make twenty twelve compatible with buddypress (I am doing this on child theme of twenty twelve), the styles of buddypress components resembles to bp-default (rather than twenty twelve). If one deletes all the css from bp.css, one gets plain styles (these are twenty twelve styles but as there is nothing in twenty twelve styles for bp, they are as good as plain). Fixing these plain styles would be like making a completely new theme from scratch (like styling _s theme) for bp component pages/sections. There doesn’t seem to be a simple workaround about this.

thanx issue solved with the update to 1.4.5

Oops. Trying again:

/**
* In WP 3.5+, get_blogs_of_user() is much slower than in previous versions. As
* a result, if you have a certain number of blogs, running get_blogs_of_user()
* will create a memory timeout. This is a particular problem because
* get_blogs_of_user() is called on every page, because of the toolbar.
*
* Ideally, there would be a way to short-circuit get_blogs_of_user(), or even
* to prevent WordPress from calling get_blogs_of_user() while loading the
* toolbar. But there is not. As a workaround, this function intercepts a key
* step in get_blogs_of_user() – the get_user_meta() call that gets all of a
* user’s metadata. If we determine that this request is coming from
* get_blogs_of_user() (which we do by examining the debug_backtrace(), a truly
* awful technique), AND that it’s one of the generic meta queries used by
* get_blogs_of_user(), AND that the current user has more than 75 blogs, THEN
* we strip all of the blog capability keys from the array of metadata,
* tricking get_blogs_of_user() into thinking that the current user has no
* blogs at all.
