For a long while, boardreader.com seemed to stop indexing the SDMB and I stopped using it. Searching boardreader for myself just now comes up with only 163 hits, all in the range January 16 to May 16, and that includes where I’ve been quoted. I know I’ve made many posts between now and May. And an SDMB search turns up about 210 posts of mine in that same January-May range.
The earliest SDMB post currently on boardreader appears to be from September 6, 2003.
As mnemosyne said, boardreader is worth a try for guests, but it’s limited.
