Time passes and
1) the massive downloads continue, and
2) none of the PC-savvy users on this site acted on my request to post instructions how to disable this. Thanks very much
OK. You want something done, you do it yourself. Following a painstaking combing through logs, I've identified the 88MB download offender. He has been banned (and I've emailed him to explain why and how to fix it).
For the rest of you, here's how you check to see if you're responsible.
1. Under the "Favorites" menu, choose "Organize Favorites".
2. Highlight your bookmark for the FE-FC Forum
3. In the box on the bottom left of the window there is a check-box labelled "Make available offline". If this is checked, smack yourself with a ruler several times and then
uncheck it.
4. Click "Close"
5. Download Firefox and stop using IE.
The next biggest offenders are downloading about 35MB a day. They will be banned next, tomorrow if I get the chance. Don't say you haven't been warned.
