So I sent some coins to Poloniex an hour ago and I am still stuck at 0 confirms...what should I do?
wait or delete it
How do I delete a transaction? What exactly happens if I wait for 24+hrs and 0 confirms still.
nothing.. either the tx goes in, or it doesn't

if it doesn't you can deletetransaction.. read dot-bit how to delete pending transaction
Hi, I had the same problem the coins were still on 0 confirmations after hours of waiting, I deleted the transaction id
and the coins came back but now I cant send them becouse if I try I get some error message that I already spent the coins

what can I do ??
run -rescan

to the others with stuck transactions, you have to deletetransactions unfortunately - if you don't kow how to do, google it or read this thread or read first post...
we know
there are a number of possibilities and we are looking into why this sometimes happens - p.s. i've only had it happen once since release..
maybe you should add nodes.. you have all done that, right?
Remember, this [software] is in it's infancy - try not to expect it to work flawlessly from day 1.. if you "don't know what you are doing", then maybe this is not for you
