Some of the links on this forum allow SMF, at no cost to you, to earn a small commission when you click through and make a purchase. Let me know if you have any questions about this.
not sure if there is a setting within the forum, but you could aslways cut and paste the main forum opening thread and make it your "favorite" link into SMF.
I have windows and use the "favorites Bar"...I linked it to the "recent activity" page and that is where I start every time. I'm guessing if you have windows you could do the same with whatever page.
I did the same thing all you have to do is go to the page that you want to open to. Then just hit the favorite bar and then you will open there everytime. Just like Mofo said.
