Hi Readers, (Updated Jun 05)
Here is the current list of the ever expanding collection of TECH buls.
Not all of the 179 buls (inc this 1) will be on your BBSs yet, but they will be
soon. At least one bul is sent each day, so the whole lot is repeated about 3x
a year. There are often updates to these files as I Rx feedback etc.
(Note for BBS SYSOPS, please delete old versions if you have no default time-
out set up on your BBS!)
