first, this wiki page tells you a bit about program hooks and how to get them started…
http://wiki.simple-press.com/plugin-api/program-hooks/overview-of-hooks/
then you have to find the hook (each hook tells you where the stuff is used or displayed)…
In the post I lnked too, I suggested which hook to use and gave the entire hook code… find that hook function in your hooks file andreplace it (the entire function) with my code…
as the post following mine in the linked post details, you have to update the username with your twitter username… that is:
data-via=”SimpleForum”
in that code (line 4 of the code segment in that link), replace SimpleForum with your twitter username…
Give that a try and come on back if you still have issues…
