I think, generally, people pick this kind of thing up as they go along.

The tick box to the left doesn't have any immediate effect, it is used to select the items that will be deleted when you select the big red cross at the top of that column. So in conjunction these are used to enable you to be able to delete multiple snipes in one go.

A yellow snipe has a snipe value below what will be accepted by Ebay, most likely due to price rises as a result of other bids having been placed on the item.

A red snipe means you are in the process of editing it.

Useful additional resources are the FAQ page and the Blogs.

Where can I find instructions on how to use GIXEN for beginners ?
EG:
When you check the box to left of your item - what does that do?
If your item is red or yellow - what does that mean?
Etc

Thanks
