For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

<br><br><i>Note - I wrote this page as a demonstration to show some features
in use on our <a href=http://www.wellho.net/course/php.html>PHP courses</a>
that we run in <a href=http://www.wellho.net/share/melksham.html>Melksham, in Wiltshire</a> - a town of 24,000 from which First have withdrawn most trains, leaving
us with just 2 each way daily. Some 40% of our customers used to arrive in the train by town ... but now it's the car, the bus or the taxi. What a shame - and what a shortsighted decision by someone (not necessarily First)!</i>
