Actually I'd prefer if people generally do not e-mail me when the website is down. Since the server is in our basement, DH and I will be the first ones to know about a problem. This was the case last night. If something is happening at our place like the internet is down or the power is out, we won't be able to receive e-mails anyway until the problem is fixed. If there is a problem with the server and we are not home to fix it, we will not be able to fix it until we get home anyway. In any case, an e-mail will not really result in the problem being fixed any faster. Of course I don't mind getting e-mails from my concerned members, but if there are hundreds of e-mails in my inbox informing me that the site is down and I can't get them until the problem is already fixed..well..I'm not going to be a very happy camper.
BUT - if you do see anything strange going on with the site such as BAD posts (pornography, etc), please e-mail me ASAP. If I am at school I may not be checking the site very often, but I do check my e-mail regularly.
