i have an old pc running XP which i am considering upgrading to a new pc running win 7. i've used winfax pro for over 10 years. does win 7 have a fax program? if so, can i convert? also, most new pcs don't have an RJ11 [?] females. how do i deal with that? or should i just buy a new multi printer with a built in fax? also, what would you do? THANKS!!!
