Yup, by the way: are there any news on the 1.7 release date? I saw from the milestones that it’s 99% complete, but it’s been like that for almost 2 weeks by now.
Found it in BP documentation for 1.7. I’ll answer my own question, just in case someone else has the same problem.
The solution is to copy the folder /buddypress/ in the BP plugin templates (complete path: /wp-content/plugins/buddypress/bp-templates/bp-legacy/buddypress/) into the root folder of the theme. I copied the entire folder for convenience, but one could just copy the file he needs to edit, as long as he replicates the file structure.
