The end users of our solutions could be anyone, which is why our product and solution output is supported by earlier browsers such as IE6.
The least-technical person that may use our products still needs to:
1) Register a domain name
2) sign up for a hosting account
3) FTP web pages
We felt that if someone were saavy enough to do these things they could also update their browser. We checked our browser statistics and less than 2% of the people were coming in using IE6, so it didn't seem worth developing for when we could offer a better experience with a more modern browser.
Ray, ask your customers on here before you take such big decisions, users on here (developers) and (non-developers) will give you a better view than reading your server stats.
The tools (extension) you sell are to the least - technical people! Dont forget that! The more savvy IT buffs will never use your extension tools. Time is money for us!
