I'm new to this board and didn't know what category my question fell in. If this isn't it I'm sorry.

I have one of those small weber grills and while it's great for sausages and hamburgers that only take about 15 minutes, I can't bbq or cook anything that takes more than a half hour because the coals die out. The only way I've done it is to carefully lift the grate with the food, not burn my fingers, add the coals, then put the grate back on (without burning myself or spilling the food). Does anybody have a suggestion for an easier way of doing this? Is there something I can buy?

Also, if nobody can give me an answer please suggest another good food message board. I would appreciate it.
