@laughoutlood,
I went out to a friends place last night and we played 2 games. All very friendly of course. I tried to put AX on the board but was howled down. They "didn't like it", even though it was in some books but not the one my friend was using. Luckily I had a blank so was able to turn it into TAX. We are trying to write our own 'home rules' as we go along. For example, we really must know the meaning of the word before we place it on the board. Fair enough. I knew the meaning of AX but they wanted it spelt AXE. [btw, I won :-) ]
What does SOWPODS actually stand for? I tried to Google what those letters stood for, but only got more confused.
Am still working on A E I N R S T. The nearest is STRAIN with a spare E. Perhaps ESTRAIN? Just joking.
