The best thing about crypo, in my opinion, is its flexibility when it comes to connecting with others through their cloud. I've been able to communicate via email, text message, video chat, or even just by sending an image of what they want me to send them! It can be very difficult at times to find other people using crypo but as long as you use your google skills (I don't) then this shouldn't be too much trouble. If someone else finds themselves blocked/blocked from communicating with you, you should have no problem finding another way around that if needed. You could always send messages directly through emails you already know how to access instead of having to go through the hassle of requesting permissions. This makes things easier since you are more likely to get into contact with the person who requested permission than if you had to request again over and over just to reach out to the same person.
