It would be really nice to have a list of things you could be alerted about so that you don't have to come check the website. Especially when it's a busy time of year and I don't have the time for things like missions, projects, RPs, and such but still want to know when someone replies to a particular conversation. It would also serve as a nice reminder.
Having the option to be sent the reminder via text or email would also be nice.

(Also, once we are out of beta mode, Sylestia should totally become an app!)
