I too would like to know the answer to the warrant question. I made a boo boo awhile ago and wanted to buy TC /TCM when it was only traded on the pink sheets in the US at that time. Instead of the correct symbol I typed in apparently the warrant symbol and bought those instead. (I had never bought warrants so was totally clueless as to what I had done) Now I don't know what to do with them?! TC has been moving up alot lately and there is some speculation it could be subject to takeover.
