A good post sir and shame if will be your only foray here.
You are right to take a step back & evaluate & asses the situation objectively. I have no idea regards your board's individual skills and gaps are but it would make sense they sit and map that put & look to recruit directors based on addressing those gaps & carrying out their due diligence on any prospective candidates.
I have said before from the outside key positives namely good facilities at Shielfield and a core support despite an awful season above a number in L2. The remote aspect is also a plus Berwick & Cowdenbeath have almost exactly the same populations, but with Cowdenbeath they have to compete with Dunfermline & Raith Rovers teams wit populations 4/5 times higher with better facilities playing at a higher level factor also in East Fife circa 25 minutes away. Berwick have more of a captive audience something to build on surely.
The key will be focusing on the key strategic areas that will bring most effect, again apologies looking from the outside I have no idea what the engagement is like with the towns people and businesses but I would have though pivotal area. I can think of a number areas you could develop, but I guess as with most clubs you then need people on the ground to implement, I guess comes back round to building/developing local engagement.
There are a number of clubs out there of similar stature it is worth Berwick going out & having a look at what they are doing and are there any quick wins/ideas they can steal.
I can only imagine how everyone around the club is feeling at the moment we only had the threat hanging twice which was bad enough not the final reality, but that has made us look at things through a different lens in certain areas.
I wish you all the very best, a lot of work to be done and likely a fair amount of change too which is never easy or pain free but if enough around the club can get on board and stay the distance I really think you can make your way back.
