>I have send sumbitted form for my file to be upload, but I don't understand do I have to wait for someones (yours) reply for upload to file@levelextreme.com?

Yes, of course, everything's under approval in those areas otherwise we'd end up with a lot of unrelated and bad entries. We apply a high standard of content integrity to the Universal Thread and that section is part of it.

However, as this section, once you submit your entry, also requires a file to be submitted, as mentioned in the javascript message box you received on save, yes, you have to send your file to file@levelextreme.com.
