I wasn't sure, but I did it anyway...

But does submitting for the first month's contest stops you from potentially
winning and/or submitting for the June contest?

Also, can you submit for more than one category?

Hey Carlos,

You can enter ANOTHER more complete version in the June contest, even if you enter a version now! Just upload another one closer to the deadline, we will make sure it works.

Also, the version you submit in June will be considered for all categories it is eligible for (so not Windows Mobile if it's for Windows, of course!), you don't even have to specify which categories it should be entered in.

Thanks,
Simon.
