In BP function reference list I have just found bp_group_description and bp_group_description_excerpt , maybe there is even more useful stuff (does anyone know more about this?). I’ll play with these two today.

*Edit: Does anyone know; HOW could this be used in a function, and are there any more of such useful for adding SEO mainly in head title and meta description (for example taking first 160 characters from a first paragraph of a forum post and adding these to meta description in head template in the theme)?:
function my_bp_title_tag( $title )
