Is there any way some action can be taken to investigate the rate of cash burn by TDX. Shareholders have waited years for further investment of what was almost $1 million and during a period of virtually no activity other than 'we are looking for opportunities' we now see less than $1/2 mil in the bank, income at next to nothing and still massive spending. The current situation is unacceptable and the accountability of the board, to me, needs investigation so shareholders know what is going on, what expenses are being met, how much work is being done in our interests.
Does anyone know how to pursue this?
