Re: Uploading documents, photos?
Consider that WordPress is going to be at version 2.8 soon, and BuddyPress has just broken the champagne glass as 1.0 a few weeks ago, and already 1.0.1 is out.
All things come with time.
BuddyPress is an opensource project just like WordPress. This means that anyone can stomp in and contribute what they’d like, and Andy as the lead developer will get the final say-so as to what makes the cut and what does not. The previously mentioned bpPicture Album plugin is a great example of that. It does the job quite well in my opinion, and is also still not 100% finished.
I think it would be a pretty large undertaking to merge the WordPress blog attachment method with the BuddyPress member profile area. Considering that if you’re using WPMU and that person has a blog, would you want to have their uploads in their blog also appear in their profile, or would it be a dedicated area for uploads? There’s really a lot of different types of configurations this could take, any/all of which are viable and possible.
All that needs to happen is for a developer to see the need, and then fill it themselves.
