Advantage: Unread posts still stay unread, if somebody closes the browser, you won't have to read all the new posts at one time. Posts can also get marked as read for a time of 9999 with the UPI2DB system. Forums which are not interesting for you, can be marked as 'permanently marked read', until you change the option. Edited contributions are marked as unread with the notation 'Edited' and additionally have another color to separate them from normal unread messages. A new search function allows one to look for unread and edited contributions only. When the Admin activated to display edited contributions in the top of the Topics, edited contributions will be displayed at the first line of the topic.
I must remark all 9999 days a topic as 'permanent read'!
Within every contribution you will find a button in the contribution title, which you can use to mark a contribution. Contributions older than 9999 days or contributions, which were written before you registered with this board, cannot be marked.
Contributions, which are marked as 'permanent read' in a forum or contribution itself or which were written before you registered with this board, cannot be marked. Contributions older than 9999 days, cannot be marked also.
No, all marks you set, will be deleted automatically after 9999 days, where you set the mark.
