Would love this feature personally. Examples how Id use it-
*Favorite members who rarely post (Casascius , Smoothie & Kialara) if they release a coin by some miracle, I NEED to know!

* If Nullius comes back, Id want to know. Ive got a bit of a man crush on true Mr Robots and from everything Ive read from others, this dude is like Elliot himself. Thats someone I want to keep up with.
*Scammers/ghosters -Normally scammers take off and are never to be seen again, but not all. If they do come back online, not that it can do much for a victim, but Id absolutely want to know.
