I find it stressful enough trying to think up a username and password when I register on a site, but getting stuck on a page demanding I upload an avatar before going further is too much. I can't get my head round finding a suitable photo, then maybe having to mess around cropping and resizing it, as I'm often told to do next. I know the importance of avatars, but all I want to do is have a quick look to see if there are any suitable members of the right age in the right country, which I expect to be very unlikely, before going any further.
