Yes, sorry, but we don't have a general "bullion forum"; you'd be best to ask your questions or start discussion in the forum that's most relevant to the question. If you want to talk about foreign bullion coins, the World Coins section is probably best. If you want to talk about bars and rounds, try the Tokens and Exonumia section. If a topic "belongs" in more than one section or you want to talk generally about silver coins (eg. comparing ASEs to foreign bullion coins and private rounds, or debating the merits of returning to a silver standard) try right here in the "main forum".
If you want to talk about the effect of government monetary policy on the bullion price, or other silver-related stuff that doesn't really have anything to do with actual coins, we do have a General Discussion section for such non-numismatic topics; you can apply to join it once you hit 50 posts.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
