Concerning the ECM client guide, you could also set a link to the corresponding forum for the cunningham tables: http://www.mersenneforum.org/forumdisplay.php?f=51

Apart from that (and the fact that it is done with Word ), I like your guide(s).

I would, but I still don't understand their purpose .
But now that I've opened for outside guides, maybe someone else can help?

Thanks! I have never tried any HTML and I don't know how to design websites. Any suggestions would be welcome.

The order of the list
Listed by completion time of one work unit:


is screwed up. I would recommend you do a test of each and then decide.

Try "save as HTML" on your word document...

A: Sierpinski numbers are numbers of the form: (\large k*2^n+1) which are never primes/always composites.
Aren't Sierpinski numbers the k numbers that are composite for any n? The way you told it seems like \large 5*2^2+1 is a Sierpinski number. It will be always composite, I think...
You already gave a good definition in the end of your FAQ. You said that "k's that doesn't ever produce primes in \large k*2^n+1 are Sierpinski numbers"

The Cunningham Tables contain numbers of the form b^n +/- 1, with (currently) 2 =< b =< 12 and n so that the resulting number is "not too big" (~300 digits right now).
There are several tables, one for each "b" and "+" resp. "-" (The table "5-" for example holds the numbers of the form 5^n-1).

In the tables of this forum contain only (at least partly) unfactored numbers. You can see

1) The short form of the number
2) The size of the unfactored part (--> the composite)
3) The effort that has been taken so far to factor that number
4) The number itself in its decimal expression.

Now, if you want to help factoring, just* choose a number and run curves on it, afterwards report your effort and factors, if found. That's it!

*I know, it's not that easy in the beginning, but after some time, it's no problem.
