I use chrome on windows.
It's easy to create a folder in the bookmarks bar and bookmark all ongoing games there. Bookmark by visiting the right page, ctrl + D and make sure you have the right folder selected. I can right click the folder and select "Open All".
I was just wondering if people have good ideas for it.
I myself have a simple textfile with urls to my ongoing Bulldog games. So for me it's a matter of going through that list once a day. With a 3 days time control I can afford to skip a day or two now and then. I also have switched on all notifications, but actually I am not really dependent on them.
