The online fantasy journal Sorcerous Signals is now open for submissions, through June 15th. Simultaneous submissions are accepted, as are previously published stories and poems, as long as it's been at least a year since the story or poem was published. Payment for accepted works is $5 per story and $2 per poem or flash fiction piece, along with the possibility of more money depending on reader donations.
