We all know what's it's like to try and give some items away to the new players but there's a race to send things before their mailbox fills up again! There's just not enough day 1 players to satisfy the generous player base!
That's why we need to extend the feature to include day 2 and maybe even day 3 players.
In a player's first day they are love bombed by so many people that no meaningful connections are formed. They can't message everyone sending them things thanking them. But people like me are actually hoping to make a connection with new players. What I've seen and probably what you developers have seen is a high drop off of players in the first few days. People join, don't get into the game and uninstall. Expanding the list to also show day 3 players also gives a chance for people to receive gifts at a more normal pace and hopefully make some meaningful connections with more late game players like myself. I'd love to know who has played the game for more than thier first day as it weeds out a lot of the people who just aren't into it in the first place. I've been able to make some meaningful connections with low level players but a high percentage don't continue beyond the first week.
The feature I'm proposing aside, any feature that would foster pairing a late game player with an aspiring noobie would be a big boon to my enjoyment of the game
