tip... if you scroll over the green check mark it will tell what it is.... mine says You have subscribed to this thread" it does ........... not........... say "you have posted in this thread"
on this forum "Subscribe" does not mean you have posted in a thread.
Subscribe makes the thread appear in your subscription list so that you can find it easy instead of having to search through pages and pages on the boards for it.
kind of like when you buy a magazine subscription or you have book marked something on your computer so that you can keep going back and read and read again and again until you decide you dont want that any more.
anyone that wants to know what the green check mark is just scroll your curser onto it and it will tell you what it is.
