Already know this will go on the list of things that will never happen, but I'm gonna throw it out there anyways!
What about a photo section dedicated to posting your gear thats for sale? No one reads words, lets be real. If you have a thumbnail of whats being sold, I feel like it would help a ton. More people would click on it and It would make it easier to find things that catch your eye. Overall more people would buy/sell, i believe.
I mean when you go online to buy new gear, it doesn't just list off names of stuff. There are thumbnails set up in grid format so you have an idea what you're looking at.
And just like with Photos now, you have like the details like Skier: Credit: Location: etc.
In this similar style you could do:
Brand:
Size:
Price:
Location:
and other relevant specs in a super organized way so that people aren't reading a wall of text.
idk this is probably stupid but I just thought of it and thought I would share haha.
