If you're using Awstats scroll down to the 'Referring URL's' box or something, and it will say (for example) http://forums.digitalpoint.com/showthread.php?t=xxx If you're using something else, please PM me and I'll be more than happy to help
Usually if you check your referral stats, then any traffic that comes from Digital Point is sig traffic or from links in your posts or others posts.
These statisctics and much more should be included in your webhosting Cpanel...don't you have it? It's pretty common part of each webhosting package... Marian
