Maybe somebody suggest something similar but I cannot find it. In gmail is one very useful option. This is star messages. With one click is possible to check and keep separate some messages from others. Is it possible to create here on frihost one button what we can use for personal booking some interesting threads. With simple link on forum home page we can then find this thread in any moment without searching around. I don't know how this is working on gmail and is this links stored in cookie or on the server but it is perfect.
Hm, the list of topics that each user is watching is already stored on the database... making a page that could view that data wouldn't be too difficult.
You'd still be getting email notifications that way, but it does seem to be the best option for such a feature, because it would be so (relatively) simple to implement.
(I do just fine by having a separate email folder for frihost emails, and having a sorting rule that automatically puts all frihost emails into that folder... The end effect is that my email inbox has an easy-to-use list of all the topics I'm watching that have new replies. (I mark all emails in that folder as 'read' when I log off of Frihost.) I also do this for every other forum I participate in.)
