[EX Q]: If you need a grammar reference, this may well serve until you find a better one. It might be of greater utility if the tone wasn't vaguely condescending and pedantic, and it eschews the panoply of actual examples in favor of definitions. To wit: the 2nd person singular present perfect conjugation of "to love" results in "If you have been loved..." gives me one (singular) example but not the rationale of when to use this. The density of the text preceding the example conjugations will require your own self-study to master (if you must) the ability to spin off a subjunctive 3rd person plural present tense conjugation.The best recommendation I can offer for this is as a companion for language learners who need a quick reference for English analogs of other-language conjugations, such as when you try to conjugate "falar" and need to know which one to use.--#

[EX Q]: Know this the web site for this gaget may tell you that the radio listings information is updated every 10 minutes. That was not the case with the radio stations I tried the emarker on. The only song information I could get was "information unavaiable check back in 24 hours". They dont even promise to have the information in 24 hours. This is not the fault of emarker my understanding is most radio stations only update their play lists every 24 hours. So the problem is the misleading information provided by the emarker site. Caution if you buy this product dont expect timely information from emarker.
