GSL Slip Renters. Do not open any emails with no subject line. A couple slip renters, who are on the GSL Marina email list have been hacked. This has allowed their email list (including GSL Marina Email list) to receive the spam adds. If you open one of these, you could end up having your email hacked and all your friends will get spam emails for Viagra from you. So far the two hacked emails are Susan Chaffin and Charles Uibel. IF you open one of these emails and you do not have good protection on your computer you may end on this list. Thanks.
