I'm looking for 5 people to help test our upcoming "Mystery Feature" :)

Here are the requirements:

- must be available to help out for about 5-10 hours

- must have a very strong understanding of chess principles (strategies, tactics, etc) 

- must be able to not spill the beans on what this is :)

If you are interested please message me and let me know.
