Thank you for your reply @Coen.
Just to clarify, what I would like to know from this post is:
1. Are there any people out there successfully using WooCommerce 2.05 with BuddyPress1.7 Default Theme?
2. If so, then what (if anything) have other people needed to change in WooCommerce 2.05 and/or BuddyPress1.7 Default Theme to make them compatible? i.e What custom CSS or other tweaks have people needed to do?
3. Have people come across any blocks to successful inter-compatibility, such as "lack of possible overwrite possibilities in the BuddyPress Default Theme" that @Coen suggests above?
And yes, I am also asking this on the BuddyPress support forum and will report back here too, to help others.
Many thanks for any help that is offered.
