I apparently need to pick better times to show up because only 2 people came today (I was a few minutes late though).
Include the Forum and Chat Guidelines under the Rules tab as a drop-down
Utilize color-change when making pencil marks
Design a dunce-cap for cheaters
I hope to see more people next time.
i donno its i believe very difficult to get many players to chat at the same time... many of them come only to play and dont give a damn about chatting or being active in the forums.... they like to play with whatever rules the admin has decided to!!
anyways as i was not available yesterday night, i would like to give my opinion on the points you mentioned...
about using colour change for pencilmarks....!! i believe the best site for solving sudoku online is the one which feels to be an almost exact replica of solving sudoku on paper...!! so basically the player doesnt feel much different from solving on paper...!!
and i have seen many people use 4-5 different coloured pens/pencils while solving (i donno what they do with it but i am assuming they must be using it for guessing) so to please these kind of players it would be great if you can add a colour menu on top of the solving board where one can select any colour for entering the digits!! so if one changes the coulour in midway, the digits he enters from then on will be of diff colour!!
another thing is for pencilmarks it would be better if you divide every 81 cells into 2 parts horizontally: one large part for the digit in the cell and the small part for writing anything like letters,numbers, signs etc for pencilmarks!! like for example you can check youplay.com or fed-sudoku.eu .... that is the standard form of pencilmark used on all the better sudoku sites!!
about cheaters!! i believe if someone is found guilty of cheating in one game then he surely has to be cheating in most of the games he has played till now!! i can see that sudokuking disqualifies the cheaters from the game mentioned in the forums... but what about the other games they have played!! its unfair to other players in the games where he/she is not disqualified!!
so my suggestion would be to if someone is found to be cheating just warn him and scrap all his data and let him start from the beginning.... kind of a punishment for cheating!! and if you find him cheating again then just ban him!!
