... after re-visiting this site and having to plough through tonnes of crap to actually find anything { tongue firmly in cheek } )
We recently had a 75 page thread started by H4ppy Chris, virtually promoting his own base recipe in a very roundabout way
I'm keen to understand the point you're making here. I don't see much wrong with the navigation or ease of finding any specific recipe. Are you suggesting something like pre-approval of posts which will only make it on to the forum if they are considered 'worthy' or, conversely, should be deleted by the moderator acting as a dictator to delete anything which isn't 'good enough' in the moderator's opinion? Are you suggesting that specific members present here, but not on CA's forum, are creating all the rubbish you allege clogs up this forum?
There can't have been a thread created recently by h4c because he hasn't been a member for several months. So how did his old thread get to 75 pages? It must be because many members are interested in the recipe and want to discuss it, together with closely related issues like whether there will ever be a book. What's wrong with that? Should any posts which are slightly off topic be ruthlessly deleted, like I assume CA must do, from what you say?
