My speciality is technical knowhow.

I host all my web sites at home on a pentium 4 based CentOS Linux server.
Built the server from scratch, installed CentOS4 (soon to be upgraded to CentOS5), configured (A)pache, (M)ySQL and (P)HP (Linux AMP or LAMP).
I installed WordPress, Joomla and Drupal. Most of my sites use WordPress, I find Joomla too rigid in its structure and Drupal is overly complex. A CMS (Content Management System) should be capable of providing you with a quickly running system – Drupal takes too much planning. If you have a better experience of it then let me know.

I also run my own postfix/dovecot email server. It’s quick but requires regular technical tweaks to keep the spam at bay but, I love it.
I built a ZIMBRA email server which was fun as it requires you to run your own DNS server. It all worked eventually but, I am short of spare hardware at the moment so will not be making full use of it until I need it. ZIMBRA email server is a full blown corporate email server system and handles spam very well. If you would like to know more then leave me a comment.
