Bathroom remodel > Horizontal wet venting questions with drawings

Hi everybody and thanks for the help (that i got 9 months ago). I though i'd drop by and post a few pics of that bathroom remodel project i started and completed in april 2012. It's not perfect but given i'm a computer guy... i'm happy with the outcome.

I'd post more pictures but can't go over 5.

Without the help of such forums i'd never been able to pull that DIY project.

Thanks again!
