I had originally joined Postcrossing just before travelling and I thought I would use it to send more cards while on holiday, on top of the ones I send to friends. And use my surplus cards from holidays to send from back home. I was pretty sad to learn that a lot of people only want cards “from country of origin” and with country ID matching - travel mode didn’t exist then. My very first sent card has a GB code and was posted from Malaysia.
I was very enthusiastic when travel mode was introduced, but wishlists make me enjoy it less so I don’t use it a lot (well not that I had a chance in the last couple of years, sigh). It puts me in a bad mood if I get someone who doesn’t like tourist cards because I am there to send tourist cards. You can send anything you want and don’t have to follow wishlists, but it still annoys me.
Since I don’t live in the country I am originally from, it is important for me to send cards from my hometown when I travel there - this is where I am right now. In the past few days I have sometimes not picked addresses because I only had a few cards at hand, and none local since I hadn’t had a chance to go buy some. Last time I got an address, I was delighted to get someone really easy going and who actually encouraged sending postcards from travels, as all I really had was spare cards from a holiday a long time ago (same country as the ID, but not my local area).
A few days back, instead, I got someone who would simply love a card from the place where I live, but I am not there now. I decided to send from here anyway, and then offer a second card when I go back.
Once instead I forgot to put travel mode and so had the “wrong” ID and also got a profile for which I had the perfect card back home. I waited a week and sent from home instead.
These examples are to say, there is always a way to handle things, and if there isn’t, your only obligation is “send a postcard” so there is no need to stress about it (in theory!).
