Yes, i know everything will be legal, but being legal will not keep everyone happy.
I have seen this work on a computer-related forum i used to be a member of, and it seemed the same people would ALWAYS get the freebies, because they would sit at home all day with no jobs, and as soon as the threads would be started, they would reply with "TAKEN, THANKS"
It was ok the first few times, but when they would take EVERYTHING, it wore very thin, especially since people were begging for what they had just taken for free because they could use it better.
I am all for it, i am just giving my opinion of the matter, and how i think things will turn out.They sound like the people who would benefit from free things the most, they obviously wouldn't have alot of money. Hey maybe you could put up a wanted ad for the things you want for free?
On another note, i was offered a free bearded dragon and tank about a year ago now, and had to refuse for 1, i didnt have the room at the time to house a six foot tank, and i didnt even really want a beardy then. He said if i didnt want it then he would give it to his mates younger sister, which i told him to do that because she actually wanted it, it was just easier for me to take it because i lived around the corner from him.
Since then i have been given a free six foot fish tank that i now have room for, and was given a very aggressive and snappy juvi darwin python because they previous owner didnt like getting bitten and was going to let it go!! That is excellent!
