Talking about wild releasing! Since it is the age of 8 second attention span, it would be absolutely wonderful to have a faster and easier way to do wild releases! When travelling abroad, I love to leave my books to new places, but tbh, I don't always know my geographical location that well.
Oh yes, the perils of releasing in a country you're not familiar with! I tend to release a lot of books when I'm travelling (lately that's been the only time I've really released books), and it's always such a struggle to figure out what state/province/region/whatever you're in, and then the local spelling of the precise location - and having served on the region managers team, I know how much work it is for someone to fix my mistakes if I get it wrong.
It would be great to have a "I'm releasing at my current location" option in the mobile version that auto-geolocated and filled in those fields, and a "click on the map where I left it" option for the desktop version (because I don't have a smartphone, so I do my releasing when I get to somewhere with wifi later on).
The other thing that's been on my wishlist for a very long time (and I know it's been discussed in the past) is a better way of organising local meetups. Actual face-to-face engagement is a great way to convert vaguely interested newbies into committed bookcrossers. I certainly never would have got so involved if I hadn't been invited along to a meetup.
But at the moment if you want to let local bookcrossers know about an upcoming meetup, your only options are to post in the forums (which hardly anyone reads anymore), or send out hundreds of PMs. Or by-pass the bookcrossing site entirely, and use Facebook or email, which means you don't catch the new members (and once the organising of meetups moves off-site, it's very easy for the meetup to become disconnected from Bookcrossing, and just be a group of friends getting together once a month - which is fine, but doesn't help the site grow).
I'm not sure what the ideal solution is, but an easy way to organise and promote local meetups, and for new members to learn about meetups in their area, I think could do a lot to revitalise bookcrossing.
Oh, and welcome back Ron - great to see you involved again!
