8. An instant message communications system comprising: a messaging resource configured for detecting an instant message having been sent by a sending party for delivery to a destination party, the instant message expressed in a first language; a presence resource configured for determining a language preference, for the destination party to receive the instant message, independent of whether any translation request has been requested by the sending party, wherein at least one of the messaging resource or the presence resource is configured for selectively clearing a cache that stores translation results of prior transmitted instant messages having been sent by the sending party, based on the messaging resource or the presence resource determining the translation results of the prior transmitted instant messages are no longer viable for context-based translation of the instant message; and a translation resource configured for translating the instant message having been sent by the sending party into a translated instant message, expressed in second language, in response to a translation request from the messaging resource, the messaging resource configured for sending the translation request based on the presence resource having determined the language preference for the destination party is distinct from the first language, wherein the instant message follows a sequence of prior transmitted instant messages having been sent by the sending party and having been translated and sent to the destination party in the second language, the translation resource translating the instant message relative to a context of the sequence of prior transmitted instant messages based on retrieval from the cache of the translation results of the prior transmitted instant messages determined as viable to the context-based translation of the instant message, and initiating the context-based translation of the instant message relative to the translation results; the messaging resource configured for sending the translated instant message in the second language to the destination party.

The system of claim 8 , wherein the presence resource is configured for sending a notification to the sending party recommending use of a third language, distinct from the first language, for messages destined to the destination party, based on identifying the third language as usable by the sending party and the receiving party.
