Hmm, what version of Vanilla are you using?I completely deleted the plugin, downloaded it from here, and installed it again.It seems to work fine for me. The tab is there, and so is the option to edit my profile.I even signed into a test account with a member role to see if that was causing the problem...I am running an unstable version downloaded only a few hours ago, however, so that may have something to do with it, though I don't think so.So you are not seeing an "Edit My Details" link? Or are you saying that the plugin made the already existing 'Edit My Profile" link dissapear?
I have also installed AboutMe and am running the en_ca locale (spanish version) and I do not see any change in the registration form.
Hmm... No, the method for adding fields to the registration form included in that version does not work.
I had done this before at one point, though it required adding something to the hooks of the theme, and a custom view.
I will be releasing a newer version with improved privacy controls soon. Hopefully I will fix your problem wocker.
