Hi Bob,
It takes some time for the DPReview mod to approve my reply. Here's my initial reply to you on DPReview:
I'm online now, but reading some news :-)
I appreciate your frankness, and will reply to you soon.
Some quick info:
I want to use free resources backed by big companies (so that they're not easy to fall; DPR/Amazon did keep the DPR forums up for nearly 25 years, if you look on the bright side) to build a successor to DPR forums at almost no cost to me. There are two options: Facebook groups and Google groups. What's wrong with Google groups is that they only allow you to attach an up to 10MB image to your post, and when you actually send the post, they further restrict the whole post's data size to an even smaller limit: you can actually only make a post with an image up to 6MB. Many DPR users are used to post original-size JPEGs exported from RAW files, usually 10+ MB in size. So Google groups are currently a no go for me. Facebook groups, on the other hand, you already know, allow you to attach an image of any size but will automatically downsize it to a Facebook-defined size, and it also allows you to attach a File up to 100MB which can be an original-size photo or RAW file. The biggest technical advantage of DPR forums is they allow you to add original-size shots in your post, which is essential for photographers to discuss and enjoy IQ.
Obviously, a Google group is more like a traditional forum / message board, but the image size issue above takes priority, so I chose Facebook groups as my solution.
sherman mentioned that Facebook groups are not searchable. Wrong. There is a magnifier icon on the upper right of a Facebook group's main interface for you to search with that group. If the group is a public group, all posts in it will also be indexed by Google. Further reading: smallbusiness.chron.com/facebook-groups-searchable-google-63661.html
I will come up with more answers, but the reasons above is why I chose Facebook groups.
Again, I like Bob's frankness and will write more later.
p.s. My biggest question for Bob: Why don't you start from an existing forum software system such as phpBB?
