I lso use the 25 count plastic boxes but I also use the 35 count softer plastic boxes. If you have marbles around 5/8 inch, you can buy a plastic cover sheet (thicker type) and cut them up into strips to use a separators and then you can get 70 marbles into a box. Here's a pic of one of my boxes.
I use AOL Browser and sometimes IE - I just right click on the mouse and 'save picture'. Sometimes, like with pics on this board, you have to move the mouse to a certain spot in the picture before right clicking to save.
There's a informal marble get together in northern California pretty soon. Sami Arim is coordinating it. Galen probably has info also. I'll message you Sami's email through the board and you can contact him. The Vegas Show isa good one to go to also.
I'm not aware of addresses being on any of the marble boards. I know I haven't posted mine on any boards. So I don't think it's any Board problem. If anyone is diligent over the years, they could have obtained most of the marble collector's addresses one way or the other. I know I keep a list for my use in case I need to contact anyone.
