>>>>>"Defining what others may collect is difficult and dangerous to any group"<<<<

Where has any reference been made to "defining what others collect"? Others are free to collect anything they want. Just not during the four days the CCGTCC convention is underway. Slab collectors who are NOT in attendance at the CCGTCC conventions will have all 365 days a year to collect whatever they want.

Why do some insist on making an issue where none exists?
