Yeah fair enough free country but there is some etiquette when collecting is concerned the same applies with selling on ebay, things you do not to piss others off. Yeah if he wants to show everyone what great figures he has seen on ebay fair enough but you cant say it wont piss you off if you look on ebay every day for your entire collecting experience without finding what you are looking for and then the day it turns up someone has told the entire community "look at this its great".
Ok if you have friends in the hobby its nice to help them by showing them what they are looking for has finally come up for sale but wouldn't it be nicer to do it in a PM or email, besides outing it on a public board might generate more interest in your friends piece and then he gets outbid on it at the end....some friend you have been, get my point.
If you think I am being stuck up then fine you have your ideas on collecting and helping friends out as do I, as for other boards its your choice where you go etc, I too think there are many people who have views up their ass in the hobby, its just nice to all get along.
