Oh dear, really? That sounds quite a flaw to me!
If a logged in user goes to register, they get redirected back to the mainpage.
If I log in as a user without a blo and go to mysite.com/blogs/create it does allow them to add one. But the problem is that in the my sites menu that then appears, they can see a link to the main site blog(which they cant acces, but even still its very confusing) as well as their own!
Surely it must be a very common occurence for a buddypress site member to want to add a blog, it seems very odd this is a problem?
Thanks
