Help wanted: Broken links (and help upstairs)

Periodically on W2tQ I highlight the four care domain links pages, e.g.:

Simon Phillips emailed me, copied below: (edited removing the actual broken links)

Peter,

I am writing to notify you of a small issue that I have just found on one of the pages of p-jones.demon.co.uk

http://www.p-jones.demon.co.uk/links.htm

There seems to be a number of broken links on this page. These are the links that I found were not working:

• Nat. MH Info Center Substance Abuse and MH Services Admin. (SAMHSA)
• Systematic Reviews: Centre for Reviews and Dissemination
• Advancing literacy: A review of LIFE 2006–2009 UNESCO
• Wearable Computer Lab
• Keldy Forest

Obviously it is not a particularly great user experience when the links of a website don’t work, which is why I thought I would bring this to your attention. I trust you will be able to fix this issue soon.

Thanks for taking the time to read this email and for creating such a useful website.

Kind regards
Simon Phillips

Simon runs a website about stair lifts, which provides information on choosing a stair lift and a comparison table of UK stair lift manufacturers.

In response I've corrected the links. I do check them with some automated tools, but as mentioned since 1998... they have become something of a monster. Considering the total number the vast majority are valid.

Before you all dash to check and get in touch :-) which would be greatly appreciated, please note that I can't necessarily respond to all such contacts in this way - but I can see what I can do ...

Many Thanks Simon!
