Ha! Over two hours to do this! Just so you know how much I appreciate CF being here for us! And sorry for the problems, as I presume the SG's are the source of file overload, in general.
OK, I've gone through all finished SG's in which I've participated and erased the saved games. All, that is, except for the infamous "Oh My God What Happened to the Zulus???" turn (from RBD1), "Fat Lady Hasn't Sung Yet" (from RBD4), and "Eighteen Techs Pop From the Great Library" (RBD7). There were other watershed turns I considered saving (like "Baltimore Shuffle" and "You Do NOT Threaten the United States" from RBD3) but decided I had to draw a line somewhere, or I'd end up not erasing anything.
I also INTENDED to leave alone all my turns in which I was the last player in the game and got the win/loss, so that the final record for each game might be preserved... only to realize that for all the games I've played, I've not yet once been the "last guy to bat". Somebody else has always seen the last turn! Amazing.
List of Completed SG's for which I've erased my saves:
RBD1
RBD2
LK7
RBD3
RBD4
RBD7
RBD11
Infantry
Utopia
Oh, I also left ALL of the saves for LOTR1 unmolested. That was the first Deity SG not only attempted, but won! Perhaps it should remain undisturbed, for future reference.
List of ongoing games in which I am participating:
RBD5
RBD6
RBD9
RBD10
RBD13
RBD14
RBD16
RBD18
RBD19
Is it all right if I wait until each game finishes before deleting the saves there? Just in case there is some need to refer back, or even (goodness forbid!) to backtrack due to file corruption, etc?
In the mean time... I'll urge all of my comrades to clear up their saves from old, completed games. I'm also not yet clear on all the steps involved in the new file uploads -- but do I understand correctly that file space on YOUR file server is NOT a problem, and that only these old games (with files stored on the forum server) will need this scorched earth "erase the old files" treatment? Or what? Do you prefer if we avoid using the forum attachment feature as much as possible? OK for small, compressed screenies? Or best to be avoided entirely? Guide us!

We need you to stay in business!
