Rypn does thread well. I prefer the graphics and layout here (large well spaced times roman on a white background....max contrast, easy to read), but I would presume that is a variable you can control (is it?). Rypn seems to me a bit more difficult to sign in to and post at, but perhaps if I did it there as often as I do here it would be easier. You could clearly do worse in terms of alternatives. But at this point I remain a vocal member of the "if it ain't broke don't fix it" school of opinion. This place looks nice and is easy to use so it just invites discussion.
