I have tried and failed to get the Tiga theme to work with BuddyPress.
Could someone kindly explain what files are needed - I presume tiga.zip and tiga-child.zip - and the steps to get the theme working.
PS I get the message: You'll need to activate a BuddyPress-compatible theme to take advantage of all of BuddyPress's features. We've bundled a default theme, but you can always install some other compatible themes or update your existing WordPress theme.
NB I have BuddyPress 1.6.1 installed, activated and working (with another theme).
