@Chris_R Fab, thanks for the detail 
I think that’ll be handy if there are topics that are similar enough to be merged as it helps reduce duplication and makes reading and finding things easier in line with what @madde says. As time goes by there will probably be a set of questions or discussions that come up, and FAQ threads or “all X in here” (like the delivery agony experiences thread) threads will probably naturally spring up.
It’s good to point out features like the “reply as new thread” option; I’ve used it myself but it’s not one you commonly get with other forum software, so it’s useful for people to know about it. Helps to keep the discussions linked and probably best left to individuals discretion as you say - the less moderating you have to do the better all round!
I also noticed you closed the what kind of SD card does the FP support thread as it had been definitively answered. This is definitely useful- it lets people know that there is an answer and that it is contained therein. It also stops off-topic discussion springing up (eg “well, it would be good if the FP supported 128GB…”) in that thread; but the “reply as new topic” button remains if people feel they want to discuss a related matter.
As @a_bet says, well done to you, @anon90052001 and the rest of the team for your work. Having a decent, helpful community is really useful for something like the Fairphone but it does take work, so well done
