Since so many seems to have issues with their alerts, I suggest you read
this thread in the help desk.
Also I suggest that people check their watched threads manually once a day to make sure no alerts from threads has been missed. (If someone doesn't know how, just look at the links just underneath "forum, groups, characters, etc." There you should see "Mark forums read, search forum, watched forums, watched threads, etc." (The order differs depending on your window size. With a tiny window, the watched threads button might be hidden behind three dots (...) hover your mouse over that and a drop down box will appear and you will find watched threads there. ))
If you check it every day, you can be sure that you haven't missed anything from groups or one x one roleplays or anything else you might be watching ^^ (And if you watch a lot of things, I also suggest you make different folders to make sure everything is easily found. Example: one folder for 'OOC chats' one folder for 'IC threads' one folder for 'general chat' etc. That way you can easily navigate in the watched thread section if you have a lot of stuff. Folders can be easily created by going into "watched threads" and right beneath the button 'manage watched threads' (to the right) there is an 'add folder' button. Click that and create folders. To add threads to folders, just click the white box on a thread, go down on the page and click 'move to folder' in the 'with selected...' box.)
