There are two sections of Drupal notes.
- Latest notes covering Drupal 6, D6. These are not really latest since Drupal is now well in D7.
- Antique notes covering even earlier versions.
Clearly these do not cover newest delopments. They may still cover some essential principles or details. I have not kept public notes on D7.
I am not a programmer and not a designer. I use Drupal for a lot of my sites, business and personal, while slowly getting more elaborate about it. I like to contribute to Drupal, but I'm not keen to mix with the profs, and no need for any high profile. Yet whatever I learn, I gladly share here.
Many of the Drupal matters and solutions discussed here do not show up here on my personal web site. They are implemented on a small number of other sites relating to the "brick and mortar" business that I am proud to participate in.
Always make a backup
Backups have saved my skin numerous times and I've been burned several times by not having a recent backup. Don't let it happen.
Even if you're not updating, make a code and database backup pair at least every month. In case your server has a breakdown, or a hacker gets in despite all precautions, you still have a relatively fresh, clean version of your site available to re-upload. Things might go without incident for years on end, but when (not if) calamity strikes, you'll need it.
Use these notes at your own risk and make backups of code and database before doing anything! Practice how to restore a site. Then get ready for the Mystery Train.
