modifications to 'building a membership area'

hello Ben and everyone,
I was wondering if you were planning in the later parts to this series to provide revised versions of the earlier code. There are a few problems as indicated in the forums. Recently, I posted a problem titled "eeek, why wont this work" relating to log-in problems. I'm still having problems getting it to work, despite the help of a few others. Anyway, if you could spare a minute to answer I would be grateful.

kind regards
