I bought in at $2.70 almost two years ago. It was the first stock I ever bought. I recently took some profits at $4.50 and I'll probably sell the rest when the stock rises.
Between ordinary project management, poor company communication and loads of attention for short sellers, I no longer see this as a good long-term hold.
In fact if it wasn't for @Audax77 's stellar work in hunting down pricing data I would have sold out a while ago.
