Do you use mailman and have you lost your admin password of you mailman list? You can easily reset it with

sudo /usr/lib/mailman/bin/change_pw -l listname -p newpass

If you have few hw resources and/or you expect high traffic on your website, here are some quick suggestions (also taken from the article Meet the Obama campaign’s $250 million fundraising platform):

• Expose your business logic with REST services
• Use a javascript framework like angularJS for calling your rest APIs and building a dynamic site
• Build a (not so) static website using Jekyll or similars and put your static files on S3 (if you are using Amazon AWS)
• use a CDN

A sample website (not hosted at AWS but home based using a poor raspberryPI2) is http://paroleonline.it
