A seek is a request for a game with certain parameters, including the lexicon, the time limit (between 1 and 60 whole minutes), the type of challenge (SINGLE, DOUBLE, 5-POINTS, or VOID), and the minimum and maximum ratings criteria that the other player must meet.
The ISC was created and is run by the player known as Carol (real name Florin Gheorghe), who lives in Romania, hence the URL www.isc.ro.
Some helpers are given the power to restrict the activities of players who have violated the rules of the site, e.g. by using inappropriate language.
Bamse, Adela, and Myrrhs are novices; Keres, Automat, and Dogberry are intermediates; Waxberry, Alehin, and Woland are experts.
Finally, players who intend to use an anagram program on ISC must inform Carol or Herve, the administrators, so "C labels" can be assigned to them.
There is also the "Multi" dictionary, which consists of English, French, and Romanian words, and has proved popular for online tournaments.
