In September 2008 guardian.co.uk officially finished the rebuilding of our website, which had started (depending how you count it) in October 2005. The project was known internally as R2. Over each of the next 26 working days I’ll be looking at one aspect of the project — one for each letter of the alphabet, for want of a better structure. Here’s what’s coming up:

• A is for article editor;
• B is for business analysis;
• C is for changing requirements;
• D is for domain driven design;
• E is for education tables;
• F is for flexible advertising;
• G is for Guardian America;
• H is for home page;
• I is for iterations;
• J is for JFDI;
• K is for keyword component;
• L is for legacy systems;
• M is for milestones;
• N is for news section;
• O is for opportunity;
• P is for pair programming;
• Q is for quality assurance;
• R is for R2;
• S is for sitebuilding;
• T is for timeline;
• U is for URLs;
• V is for video content;
• W is for Wiimbledon;
• X is for XL;
• Y is for YAGNI;
• Z is for zones.

Tomorrow I’ll start with A.
