I know this is probably not the only reason but could it be that more people are using mobiles and tablets these days and not finding it as easy to navigate to Freeones with these devices? I've just tried accessing the Freeones Forum on my phone and it took me a few attempts to find it from the homepage. Maybe easier access and better layout on mobile devices would bring more people to the board.
I know with SEO and Google rankings, if you've got a more mobile friendly site which is easier to navigate, it bumps you up the rankings Could the marketing of Freeones have any effect on the people coming here and staying here? I dont know! :dunno:
I guess some members have also moved on from the forum because of life changes as well, whatever they may be
I remember when I joined back in 2009 the board was a lot livelier than it is now. I think if there are more people on the board bouncing more ideas, views and topics around it you will generally get more of a dynamic community and interest if that makes sense
That's my 2p worth anyway lol
