First:  Is there any way at all to drop a thread (or ten) from the "My Discussions" part of my page?  There are so many that I have lost interest in, or was wrong about who I was posting about, etc.  I would love to clean up my page a bit and get back to my basic crushes.

Second:  Is there any way to simply add myself to a thread that I have nothing to contribute to at the time I first notice it, just so I can keep up with the model?  Maybe an extra tag at the posting page?

Thanks in advance for all of the great work you people do here.  It is appreciated.

First: This has been asked before and the answer has always been ....No

Second: You could try to add the thread to your Favourites instead by liking a post in that thread

You can access your Favourites by going to My Discussions and looking for the link there on the right hand side

First - per Foggy, nope and not a forthcoming feature, probably ever. And yes that gets asked a lot.

Second - You can also access favorites via your profile, it's a handy way of keeping threads you want to remember for later.
