I have time, and didn't invest too much in this, but this company has less than 300 shareholders, and it is not uncommon for a company to go "dark", under the 12g SEC rule basket, which their last 6K hinted at, which could save them a lot of money, how much they would spend I don't know but some companies spend up to $100,000ish range to comply with yearly SEC reporting, which is a lot for 200+ shareholders.
Going "dark" does not mean they are going out of business, closing doors or any of that, it is often a wise move to save money, as is going to the pink sheets is sometimes better, due to more difficult liquidity, for the share price to rise.
So I'll wait, it's not going to kill me one way or another.
