This would be my suggestion as well. Don't even bother with the "All Pings" tab unless you want full history, but you can at least keep the "New Pings" cleared by hitting "Mark All Read" on occasion.
As for the rest of you smart alecks, the poster asks a series question, and all they get in return is a hugh number of sarcastic posts.
Thanks for your nice response also.
The site is a little confusing sometimes even though I’ve been registered here for a few years, I thought somehow the pings were purged, but I just happened to look at my pings and they went on for pages, I thought it was taking up space on the server and there might be a way to delete them to free up space, obviously I wasn’t thinking because to delete them would also remove the posts, so that was my duh moment when I realized that.
