Interesting idea. You should include categories/tags for the offers too in order to make search easier.

Thanks for your feedback. It was something that was in our plans to do when we were in the creation process of Coinmad.

The only reason we decided not to include categories from the start, was because we wanted to emphasize on the fact that Coinmad is not another typical "buy & sell" website, that people visit in order to find an item they already know what it is.

We thought that a simple offer search would be enough, in order to promote the diverse logic that is the mainly characteristic of the project. Our main goal is to make people familiar with the use of "Insert Coin" procedure, without having in their minds something to buy in particular.

Since many people believe it's necessary, we will include categories in the near future. We have some cool ideas on how to do this, in order to fit with the environment of Coinmad.

One of our future updates will also be the addition of Greek language as an option.
