No rating yet Subject: Re: [ADMIN] Should we allow attachments? Author: Shak Ismonov Date: 2008-04-23 21:23:30Dear all,
Please count me as one of those who is against the attachments. Even though, I prefer to use pictures to ask questions or to explain anything in this post, I never had problems to upload them to FREE storage web sites such as www.box.net and include an external link to that file. What the answer providers are saying is fair enough: attaching pictures should be left to the asker on how to handle it. This mailing list has been successful without any attachment capabilities.
