I've had problems with the tinyurl type systems from time to time, but they work 99% of the time. Normally you never need to use tinyurl type links on Glamour 1 since the links are embedded directly into the code and thus can't break apart as they often do in emails. However, for providing a link to be inserted in an email, the tinyurl type links are definitely the best way to go. Nevertheless, I usually provide both in the email as well as specific text for search engine use.
A few years ago, I got tired of giving free traffic to the tinyurl type systems, so I implemented my own "tinyurl" type system. Anyone with a website can do the short links themselves. If there is any interest in this idea, then we could start a thread in the tech system to discuss it.
As for the Loupe system, they work pretty well, but $70 is a quite a bit for something that you can check very easily by just taking an appropriate photo and examining it on your computer screen.
I've only had to clean one sensor screen in over 5 years of using digital SLRs (Canon 10D, 20D etc). I talked to other who had spent several hundred dollars on different solutions. I opted for the easiest solution that seem to work 100% of the time. I took it to my local camera store and for $50 they cleaned it. Each cleaning pass they would show me a resulting photo and we carefully examined for dust spots. After several passes we got a 100% white photo with no spots. Its been 6 months since that and no spots have returned.
