You are invited to join the WinSen Users Group, a forum for current and prospective users of Sentinel Systems' WinSen products. Our experience tells us that everyone benefits when customer suggestions are incorporated into our products. We have a more marketable product and you receive enhancements that make it easier to run your business. An e-mail account is all that is required to participate in the forum. You may visit the groups.yahoo.com/group/winsen-users web site for more options and to view archived messages, web links, etc. PLEASE NOTE: In an effort to protect our members from unwanted solicitations (SPAM) the group moderator approves all members. Depending on when you join it may take a few hours for your membership to be activated (longer on weekends and holidays). Thanks for your interest in our group.
