Re the avatars being stretched, yes they definitely are stretched and I can't figure out why at the moment. However if you re-upload the avatar that seems to fix the stretching problem (it did for me anyway, I think there must be a way to figure it out without doing that for everyone though, there's probably some option somewhere that says 'set avatar dimensions to 80x80' which is what it is right now (80x80) which looks stretched if your image isn't 1:1).
Not sure about that, if you could provide a screenshot maybe that would help, cheers.I hope this isn't seen as a negative post! The work you've put into this looks immense. It's just a lot of the style of the older forum that prompted me to become to become an addict here seems to have gone. Unfortunately, I can't look around the rest of the site because the section under the contents bar is aligned completely to the right hand side both in my primary browser Google Chrome and also in Firefox.
