Sorry to start another thread on my conference woes but I have a more specific question.

I was due to travel to Montreal for a conference but have been grounded due to volcano flight problems. The conference offered to put a copy of posters (for those Europeans unable to travel) on their website and I thought why not.

I've since been thinking of trying to present the data elsewhere, which is where the problem comes in: other conferences stipulate the data must be unpublished, but if it is published on another societies website and I had an abstract accepted, which will presumably go in the conference proceedings, does this make it published?
Would asking to have it removed from the original conference's website make a difference? (and if I do should I be honest and explain I want to use the data elsewhere or would that look bad?)
I could contact the second conference for advice, but I don't want them to look unfavourably on my abstract submission!

As the poster stands, the abstract is slightly different to the one originally accepted, due to the abstract being written when I had less data. I'm still collecting data so it could all change slightly again (to make it slightly different from the original poster, though probably without changing conclusions) Dunno if this makes a difference.

Sorry for all these rambling questions. I just don't know the correct conference etiquette (if even there is one, being unable to attend due to unprecedented grounding of all flights is slightly unusual....) Thanks for any advice.

Hi Catlinbond, I think it should be ok so long as your abstract is a bit different and you are presenting improved/slightly different data at the second conference. It is a poster after all, and I'm not sure abstracts count as publications in that sense. I know several people who have presented the same poster at different conferences. You might try contacting the organisers of the 2nd conference to see if they count a previous poster with less data and information as previously publishing your data and then decide what to do about your current conference.
