Do you have a specific question or problem, OTHER THAN HOW TO TURN OFF THE CAPS LOCK? In general though, if you wanna use your arms (which is my personal preference), try the inner elbow. If you can't see anything there, try tying off slightly higher than the inner elbow and pumping your fist a few times. Then lay down on a couch or bed, but let your arm hang off the side (so that it is lower than the rest of your body). This should help bring the vein to the top. You can also try taking a hot shower, or warming your elbow (or desired location) in some other manner (heating pad, etc.). Once the veins are brought up to the top you can usually feel them with your finger (you must barely touch your skin to do this, just barely slide your finger across when feeling for them). Other than that, maybe check out the FAQ here on bluelight or go to the heroin section of erowid and they have links there pertaining to safe injection. If you have any other specific questions, post here and im sure someone will help you out!
