Just wanted to take a second and let you know about the "New Graphics Site" virus. This has hit a huge number of Yahoo boards and sites, this includes many many Freecycle sites nationwide. Many of the sites that have been hit have gone on full moderation which means every post has to be approved by the moderator. It is a major pain to do this. Some of the sites hit have 3000+ members. Luckily, as of right now, Hanover Freecycle has not been hit.
The "New Graphics Site" virus is a worm that is ACTIVATED WHEN YOU OPEN THE EMAIL, there is no attachment, merely opening the email sets it working. The subject line on the email should read "New Graphics Site" or something to that effect. Do not open it. Opening it attaches it your address book and sends the worm to all the addresses in your address book that have a "@yahoo.com" or "@yahoogroups.com" ending. It is not supposed to delete files or anything. Symantec (Norton) Antivirus rates the worm as a Threat Level 2 which is next to the lowest threat they have. I think its more of an annoyance than anything else, but it seems to be a major annoyance!
If you do not have automatic update on your virus software, please update ASAP. If you do not have virus software, find some Symantec and McAfee are two good ones. If you have comcast.net, they provide McAfee free to subscribers. I have Symantec right now and have had no problems (yet!).

Hope this helps. If in doubt about an email, don't open it! Especially attachments!
