multi-tabling is very effective and all but i feel like you NEED to have a large computer screen to be watching each table at all times. so if you have a 19 inch screen or less, try not to play more than 2 tables at a time, this becomes a HUGE hassle to keep clicking back and forth and giving attention to numerous tables at one time without seeing them at all times. I have seen some friends multitable and win alot of money at one time, but they had a 21-27inch screen and had 4-6 tables going at once BUT THEY could see all of them at one time.
