farktography dot net is a separate site from fark dot com. the contests run on Fark on wednesday night starting at 8:00 EST. to enter at that time you must have a TotalFark account.
TotalFark is a premium section of Fark and requires a paid account. the subscription runs $5.00 a month and there is info here http://cgi.fark.com/cgi/fark/totalfarksignup.pl
after the contest has been on TotalFark for a few hours it goes to the main page of Fark where everyone can see it. at that time, if you have a Fark account (either regular Fark, the free account, or TotalFark) then you can vote and /or post an entry of your own. while the contest time is consistent on TotalFark it will vary on Fark but usually is around midnight.
to post an entry you need to have the image hosted somewhere on the web. the image should be around 50-70kb and not bigger than 700 pixel wide and 1200 tall. images larger than 200kb will be rejected and wider than 700 pixels will be resized.
ok so far? now go to the bottom of the contest and find the comment box. enter your user name and password. in the comments box enter and enable voting. click “preview” or “add comment”. personally i preview then post. if all goes well your entry is there for us to vote on.
BTW Fark has this really neat feature – the scratch pad where you can test your posting. http://forums.fark.com/cgi/fark/comments.pl?IDLink=69
hope this helps.
