Why not keep 1000 tabs open like anyone else?
Also like someone here mentioned you can decide to keep it open as a tab but it's not actually something that I would do since I don't like opening tabs down except it's very necessary.
He said posts and not threads. If he has many tabs for each, do you think he may not forget the posts? He may forget the post but have the thread.
Also having many tabs on is not advisable because you can not easily know the tabs if it is getting too much.
If this forum can create a board for it will be good. The board will be for people to create just a thread and use it for saving something like this.
