Hello there, and welcome to T-Net. First, you should probably post something like this in "What is it?" instead of "Help!", because this is more of a website issues thread and "What is it?" is for identification. Second, I'm no expert on meteorites, but odds are that it is not. It looks like it might be obsidian or some other type of volcanic glass, maybe even a piece from the inside of of a blast furnace. A lot of meteorites are pure metal, especially iron or nickel. Does a magnet stick to it?
1st - I noticed this was your very first post - so, Welcome Aboard mikky! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forum: Select Your Area.... for information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country). You might also consider adding your state (or country) to your displayed profile (SETTINGS -> EDIT PROFILE) - members may have more success helping you (your location may help, etc.)...
