yeah, there's no need to make another thread, you can always update it as you go through different bud.
The Stash Jar forum is for more than just what you're smoking on, though. If you read the description, it says; This forum is where you can discuss and post pictures of your current stash as well as specific strains. You can also post about where you smoke your stash, too. So, you can also post discussions about strains. Some people may want to make a separate thread for a certain strain to help people who are trying to do research on it. They can post about where they smoke as well. Yeah, you should only need one "here's my stash" thread, but limiting it to one thread per member would prevent people from being able to post strain-related questions and anything else falling under Stash Jar.
