I've used about 2 MB so far for about one-6th of the letter A. At this rate it will be about 12 MB for A and maybe 250 MB for A-Z. Maybe.
That would be okay, except that the forum only has about 150MB of space left before it starts wiping out old attachments.
As I said, the more you post attachments, the faster you speed the older attachments to their demise. Which is fine. Except eventually that will also include the attachments that you started with. So, I leave it up to you if you want all your efforts to be for nothing.
I'm not trying to stop you. In fact, I find these posts to be very useful. I just want you to know what you're getting yourself into.
