Hi John,

Thank you so much for your insightful message and consideration.

We will soon update the "Fixing a Bug" section to include bookmarks and 
branches, which as you correctly pointed out, are easier and more 
approachable methods for users that want to contribute and don't need to 
deal with multiple patches at once.

The queues section was the first to be written since most of us are 
working with queues and we feel comfortable with those.

I'm sorry for your issues and I hope that this little bump in the 
process won't prevent you to continue contributing to Thunderbird 
whenever you want.

We will get on this right away and improve the documentation for beginners.
