About the PAD thread, ill take this point from life experience.
The world can be a cruel place, if you post a picture that might not be overly awesome, be prepared for constructive criticism, and take that with you, when you go out for your next shot - and your next shot will be even better, and so over time, this helps a lot.
Hell, when i started as an apprentice back in the day(even tho i say so its only 5 years ago), i thought i had the worst boss ever, he would be such an ass if i did something wrong or maybe broke something by accident.
But now when i look back at it, i think i might actually thank him, he helped me become who i am today, it takes a lot these days to throw me off the hook, and i think i can thank him being an ass for that, i am now prepared for anything anyone can throw at me, and still smile at the end of the day.
So my point is, if your new, or experienced, it does not matter, if someone has constructive criticism for your photo, take it with you, every time im out shooting i learn something new, and i like it that way.
about the Forum.
This forum i think is evolving nicely as it is, but i does need some rules that the moderators can hold the users to, also needs more mods.
That's just what i think anyway.
