This is an interesting thread and I have been following it for awhile to see where it leads to since apparently the
Chocojournal will probably never be released.
I installed this on a test site and it looks okay. Thought like above the Avatar didn't work, even with a differant postbit file inserted into the new journal template. Must be something in the php page (still searching to find out why).
I will mess around with a bit to keep this idea going for those interested and also post any changes or modifications that I do.
Cheers
Mike
