The policy is that if its free and/or if its something thats realy tiny business and dirt cheap then you may post about it, also if its somekind of breaking industry news you may also post it (but if you do you should maybe consider dropping a line to admin yyourself and he will consider it). Otherwise buy advertisement space, highend does not soley work on goodwill you know.
Either way im ppretty sure your anouncment does not realy fit any of theese categories... well investigate. it will pop back up if we deem it valid.
