I am sorry about this disorderly mish-mash of pages. This site hosts a conglomerate of pages which were hosted at different sites I had over the years at Geocities and other free hosting services and I have just thrown them together here. Maybe one day I will get around to organizing them and giving this site a better structure but it may be that if that day comes I might just delete entire sections as unworthy. In the meanwhile this site remains like the shoebox full of old photographs which one never got around to classifying or placing in an album but where once in a while one likes to rumage if only for a trip down memory lane. Maybe among all the junk you can find some useful or an entertaining tidbit.
