“When I have an idea for a project or something like that, I email it to myself in order to make sure that I remember it later or when I need to search for an answer to some question etc…” student
There is an online service called Nudgemail that allows you to send email reminders without signing in or having to open your own email account if you are parted from your own technologies for any length of time!
The company has put up a Nudgemail YouTube video that explains how you can sort out your timely reminders or link it up with Google Calendar.
