1) Post a photo (You can only post ONE photo) that is based on the original poster's theme. For example, if the OP says that the theme for this week is the P-61 Black Widow, then post what you think is the best photo of the P-61.
2) The deadline for submitting pics is 24 hours after the thread started. All pics submitted then will be disregarded.
3) After that, the OP will put the submitted pics (Along with the names of the users who posted the photos) in the very first post for everyone to see.
4) The OP will make a poll that will run for three days. The user with the most votes will get to choose the theme for the next POTW.
