.. As an additional incentive for 'Caissa' members to remain as
paying members; someday,{'over-the-rainbow'}.. when your
Website gets most or all, of the 'good, vs. lousy move' 'kinks'
worked-out, in your 'best' designated online chess-server; it
would be nice if you were to offer current members, a year's
{additional} free membership; provided that person can 'beat'
"Rasputin" {or 'whomever'}, a specified number of times, in a
given time period, at a pre-determined time-control!
 
.. I've even given this hypothetical idea a name{!}.. Call it,
"The Caissa Challenge"{!}.. as we're almost All 'suckers' for
being "challenged," with an incentive in 'the offering'!; even
if this {idea} doesn't 'take effect' for another 12{?} years,
when the best chess-software, will presumably be 'unbeatable';
as in, 'little-or-no-risk' to your company's financial 'bottom-
line'{!}

As a rule we do not give prizes or rewards for "winning" chess games because this unfortunately leads to rampant use of chess computers.
 
Rather, we prefer to reward "participation", that is someone using the site frequently and participating in events and tournaments.
 
Any suggestions you have for "participation" awards are welcome.
