Quote ="mwildcats"All im saying is that why has it needed the return of a piece of paper with 100 shares written on it to make people invest in the club.'"
Why indeed?
Why do people spend money buying squares of turf if a club moves to another ground when they've got a garden full of the stuff anyway? Or other mementos that have neither practical value nor the material value for which they've paid well over the odds?
It's symbolism, nothing more, and nothing less. An important element in life, with little or no material value, but something which serves as a token and reminder of loyalty and commitment.
In purely material terms there's little difference in this particular case between share ownership and donation, as you've stated. But there is a significant difference at other levels.
Vanity? I could think of other ways of making a more lasting impression on people who are swayed by appearance than by waving a piece of paper designating 100 quids' worth of Wakefield Trinity RLFC shares in their faces, though vanity in the other sense of the word may in this case be closer to the mark.
