Updated 12 July 2012
This heading "Drupal" contains my newer notes on developing several Drupal sites. Putting the notes on my site helps me to access them faster when I am moving around between locations. At the same I hope they can benefit others as well. I learn and benefit a lot from forums and searching and finding the experiences of others - I hope that my notes can help as well.
This newer set of notes is valid for more current versions. They all mention the core and module version number that they refer to. They are also updated from time to time and the date of the update is shown.
Check first if core and module version numbers that are discussed here jive with your actual versions. If version number do not fit, just be aware that the note may contain useful details, but may not be fully applicable to your version.
Beware of the "drupal antiques". These are my older notes. They may be severely outdated. They do not all show version dates. They do, at times, show some signs of frustration when things were not going as expected. :)
