Perhaps the 2nd worst sin on the web behind lack of connectivity is lack of interactivity.
SAM here has never been very concerned about comment interactivity, relying more on 'beltway' interest and perhaps google referencing. Now we realise after 2 years (derr) that the captcha code for entering comments is particularly intimidating. We have been told this before but never worried about it. It's the host server design actually.
Now that we have worked out the captcha code from the USA based host server we provide some basic guidelines for users after working it through. It's not so hard after all.
In short, focus on the LARGE capitalised numbers and letters strictly from left to right no matter if it is high or low on the box. Just ignore the little numbers, concentric circles and lycos branding which are the very confusing items.
If you don't pick it first time you get a prompt in quick time. Here are some examples: First and Third are right. Middle one is no good.
1. Correct going strictly left to right, only large capital letters and large numbers. Notice tricky capital C is correct. Ignore little numbers and lycos brand.
2. Below, incorrect. 8 low in the box is correct going strictly left to right, error is last large capital letter J not K.
3. Correction of 2 above, ignore the little numbers and lycos brand
