I know this has been talked about before but I will bring it up again:

I would really really love to see some kind of feature that would allow the price (by formula) to remain variable until the time when the physical meeting takes place.

Fixing a price days ahead of time will always leave one party disgruntled. It helps noone. It also increases the occurence of people just not showing up greatly. Adjusting the amount of fiat cash involves cumbesome calculations (I did this today).

Allowing the price (amount of coins to be transacted) to adjust by pricing formula would solve all these problems.

Let me add that it would probably make me actually use the transaction feature (instead of avoiding it like now, telling people to bring a wallet and do everything on the spot, which is cumbersome and can lead to misunderstandings) and therefore generate revenue for the site (currently the site has close to no revenue from me).

Are there any problems with this approach I'm missing? I don't see any substantial drawbacks of offering this, only advantages.
