[Harp-L] question about how to find a subject in the archives and do i need to sign in on home page

[tom hunt]

hello my friend
i used to read things in harpL some years back
time passed and i registered again
when i look at the home page i see no place to sign in ( unless sign in is not needed)
also when i click on archives
    i see no place to enter a subject to study

for example if i wanted to look up mega tone wezo 45 amps
         or  fender princeton 68 re-issue mods
          i see no place to do that
it seems i can only open the archive and look through it at random
            is this the case?

i will include two attachments of the screens i see i i visit harp L
thanks for your patience
tommy
