It's a pity the link to v.5 forum has been taken off the site (unless it's so well hidden I can't find it). I know it has been closed to new entries, but there have been some very knowledgeable discussions there, with very experimented fellows. I, personally, learned a lot. I'm sure there's quite a bit of technical material that's still relevant there, despite the product's evolution.

For what it’s worth, I use a little-known but highly useful piece of Google-fu called the “site” constraint. If you enter into Google “my search terms site:forum.macrium.com”, you’ll only get results from that domain. It’s useful if you’re trying to find something you saw before and remember what domain it was but not how to get there, or if you expect that the most relevant results will be at a particular site. I’ve found V5 threads like this in the past, but if you just want to browse the forums, I’m not sure that’s possible.
