Nice idea and great offer for the newbies that are asking someone to post their details for their own ANN thread. But you can't also avoid those generous people that are appreciating help even it's for free, you can put some tip address on it too.
I suggest to just quote it for them. And when the time comes when they reach Jr. Member and the images begun displaying then you can remove your post to look much neater. This is a much better approach so they can easily make changes especially it's an ANN thread. I have seen some cases where their boards are quiet cluttered and made new threads which they can moderate by themselves and this results to confusion to those people who follow their project.
I saw this and yahoo has been doing this with his campaigns as most of the campaigns his managing the owner of it are newbies.
