In my opinion alot of the "banter" went by way of the social groups and PM's. I really don't understand joining a social group that is topic specific. If it has to do with Fords place it on the main boards.
If someone helped you out by answering a question or offering a solution to a problem that was posted on the main board, reply with your respons/thank you on the main board. No need to send the person a PM and take the "banter" private. Common conversation/banter is how everyone gets to know each other. Trust me when I say just from reading guys comments on this board, not comments directed at me, just comments, questions, suggestions, replies, etc, you can tell quite a bit about a person.....good and not so good.
As far as posting photos, it really is quite easy and is as simple as reading the directions and practicing a time or two.
