Upload space proposal.

Before a recent clear-out I had uploads going back years, some of which were however still useful e.g. mission files or graphics like graphs etc that were used to illustrate some point in some thread.

It's very easy to run out of space for forum uploads. So, might it be possible to implement some system whereby it could be possible to pay some small amount to have increased upload space?

Edited to add: apologies, should have added this to the suggestions box thread. Please move if appropriate.
