I just tried signing up for the local Visual Studio User's Group. Their site has a location in which you enter your email address and click a "sign up" button. Which promptly returns an error.
Needless to say I am eager ... nay, inspired ... to become an an enthusiastic participant in this group.
It would take me, at most, 3 hours to write a highly configurable, robust (the criteria requiring most of those 3 hours) service to validate all the pages and operations in a web site. If your choice is to risk letting your company or group look foolish, why would you not spend the 3 hours? Why would you not spend a week? Why would you not spend a month?
Companies that place little value on their public reputations should be avoided because they have no reason to produce exceptional products. Good companies know this, and smart consumers know this. You should have just two interactions with companies that obviously don't value their reputations ... short their stock, and open a competing service.
How expensive is it looking now?
