@sms,
Butrflynet had a thread with quite good "how to" posts - I'll try to find it to give you the link.
One of the difficulties here is, at present, the search system is not as great as it used to be when the site started, for the reason that the early system, while wonderful, is nigh impossible now with the tremendous backlog of posts and subjects.
Robert Gentel, the site owner (earlier known as Craven de Kere) has plans to improve the search function, but that will take a lot of his time that he doesn't have that much of.
In the meantime, you can often find subjects by putting a keyword (well, word that interests you) in the little Search Forums window to the right of the New Posts page.
So, the next thing I'll do is put A2k help into that box and see what comes up.
Another way to search is to put words of interest into the small Google Custom Search box up in the dark blue banner.
I'll be back when I find Butrflynet's thread. I'll eventually find it even if I have to go and put her screen name in the google search box and then click on her name in whatever posts come up, which will bring me to her Profile page, where I could then look up all her topics...
There is also an A2k blog, that Robert writes when there is new stuff going on re the a2k website. You find that by clicking on Blog at the very bottom line of the "footer" at the bottom of the page.
There also may be some help link on the log in page - I never look at that page since I am always logged in..
