I don't see how 'workshopping' on a poem is 'publication' - Neighter do I see how a poem, once 'finished' after some editions done on it in here could be called a 'publication' - not even when its left on the board afterwards. There is also that something thing called 'loyalty' towards those surrounding you in workshopping surroundings ... they might want to 'see' the finished result of the poem. Its decent to leave it once its finished. Any idiotic publisher telling you that that particular poem on that particular workshop is a published poem is a mere fool not worth having your work published with him.
What is a published poem? Its a poem somebody (a publisher) has put money into with the distinct purpose of ditributing it so that he can make money. Once somebody has made money off your poem, only then it is a published poem. Anyway, long story! But the answer is - no poem workshopped on a workshopping board is a published poem - not even poems displayed on webpages (like mine in doc files and of which I hope a million copies have been made) are 'published' poems!
Hope that's closer to the topic william ... yes that question of publishing one's work! You can't make money out of poetry. Or only a view make money. I think the poet also has to understand that part of his 'gift' to write poetry belongs to the 'society' ... like one pop song says 'Its time, its time ... so let's give it back'.
I'd say, dear poet, be kind to the world that surrounds you. Oh come, give it a poem ... free!
Aah what am I talking about!
