Is the prefix web#_ required for each username? I read in the docs this could be changed - I deleted it for three reasons:
1. In transferring all the sites onto the new system, I wanted to keep life as easy as possible for my clients by making as few changes as possible
2. I wanted to keep it all as easy as possible for myself by having as few new things to explain as possible
3. I can't see any reason for such a device, and none was given in the documentation. It's not a distinguishing feature - I spell real names properly, usernames are all lower case and passwords must contain at least one digit, one non-alphanumeric character, one upper case and one lower case letter in a statutory 9-character password.
However, I am having all sorts of niggling, seemingly random, problems with email services so if this is at least a partial cure, I'm interested.
