Just joined the forum after my recent purchase of a K-r. By the way I was a prolific user of a K1000 between 1990 and 1995 (when the thing was stolen). I'm sure I'll be able to pick up a lot of information on this forum.
Hi Krishna -- welcome to the forums. Pity about your K1000 (do you have any of the old lenses?) but welcome back to Pentax, and enjoy shooting digitally. You can indeed pick up loads of useful info here.
