First off, welcome! Can introduce yourself to the community and show us pictures of your G6 (we love pics!) in the Intro forum: https://foreverpontiac.com/forum/3-introduce-yourself/
If you're looking to be a part of our monthly Pontiac of the Month contest, typically the entry period runs from about the 15th of a month to the 22nd. Our contests run the month before so July POTM was actually started on June 15 with entries. Then we do voting from the 22nd to the end of the month.
The topic here that you posted in is the voting topic for our July POTM. Our August POTM will kick off the entry period on July 15th so you can certainly enter then . We typically send out emails for when each the entry and voting topics open up so be sure to opt-in to our email newsletter to receive those!
