I have taken a look at Sedat's patch and the design and actual code look good. I tested against Roller trunk and everything worked fine -- there are a couple of small fixes in error handling and email word/formatting that I will make before committing, but overall it is ready to go.
I wrote-up a proposal based on his work here: http://cwiki.apache.org/confluence/display/ROLLER/Proposal+Email+Registration Please review and comment on this proposal. - Dave
