I built and maintain this site on a daily basis for a Society with nearly 3,000 members. The site is built in Drupal 7. It includes an online ecommerce facility (Drupal Commerce) linking to a WorldPay secure server. 

Special features include: 

• Member database managed online (using the 'RedHen' system), with full member-login features
• Integrated online accounting system
• Document storage, calendar features and online registration
• Emailing to lists

I have built and maintained this site for a London-based law firm for many years. It was recently upgraded from Drupal 6 to Drupal 7. The visual was designed by a third party designer, and the theming done by ElfgenPick in Germany.

I built this site in Drupal 7 and maintain it on a daily basis, for a Society with almost 600 members. This site offers integrated member and admin facility via a frontpage log in. It also offers a fully searchable database of adjudication professionals - those members who opt in to be searched.
