It's quite simple: 

• Be the last member to post to this thread and  you're 500 Drachmas richer.
  
  
• This contest ends 3rd of August 2017 09:00 UTC
  
  
• The last post with a timestamp before the 3rd of Aug. 2017 09:00 (UTC) wins
  (posts with a timestamp of 09:00 or later will be disregarded).
  
  
• You may post as often as you like.

No complaints please about ...

• slow connections
• sudden lags or latencies
• or dogs that ate your homework

... they all fall under the category of "it's a mean and unfair world". :-)

Good luck to the finalist (in that very sense of the word! :-)

Cheers
