Bought some CLAM on Poloniex today...
Attempted withdraw to wallet...
Wondered why it showed Pending even after 20 minutes...
Then remembered Poloniex is broken.

Open a support ticket and wait! I'm waiting on a few deposits in. It's been 6 hours.
You think that after they lost 1800 BTC... they would at least bother to fix the CLAM wallet or ask Doog/X for further free assistance.

O well, shameless plug:
