I am not sure, there may be some savvy people here that could tell you another way to follow a tag, but untill communities are implemented in steemit, just manually check out the #steemsilvergold tag from day to day. I usually check in to the tag daily and try to catch the new posts. All of us who are members of the #steemsilvergold community actively follow each other so we see when one of us posts into the tag. In the future there will no doubt be a post about the 2018 coins and the actual payment this year was made through @phelimint s website. I would also recommend following @phelimint and @silvergoldbotty to see future posts about the coins, as well as some great other posts as well.
